RE: dealer run around
The 1500 truck in question has the Z82 package so it comes with the RPO code MYC which is the 6L80E tranny.
The 6L80E six speed tranny is rated up to a 8600 lb GVWR vehicle and has a 14000 GCWR rating and can handle up to 430 ft lbs of engine torque according to '11 specs. The 1500 truck crew cab truck has a 7000 GVWR.
All truck owners regardless of percieved towing experience should be given his trucks full towing/hauling specs that he paid for.
Now its up to the OP to decide if the trailer has a 7800 GVWR or is 7800 lb dry weight. Big difference.

RE: dealer run around
this from a previous post.
yes the GVWR is 7800 and the truck I'm currently looking at is a 2012 silverado with a rear gear ration of 3.4 engine 5.3 v8 crew cab
I tow a 7640 lb actual weight trailer with a '06 1500 crew cab 4x4 chevy 3.73 gears.
First the 3.42 axle is as high as GM offers for the 6L80E tranny. A higher 3.73 or 4.10 gear is simply not needed with the new 6L80E tranny gear splits that are closer to a 3.9/4.xx gears depending on tranny gear selection.
Looking at GM online ordering guide shows a loaded crew cab 4x4 LTZ has a 1700 lb payload. GM also says the same truck has a 9500 lb tow rating.
Apparantly your trailer has a 7800 GVWR which means it probably weigh less after loading. Now if the trailer is 7800 lb dry weight then towing in the hills will be slow with lots of RPMs.
You mentiond using the trailer 4-6 times a year in your home state. By all means the truck will work fine and you certainly don't need a 2500 truck for that 7800 GVWR trailer.
I have lots of horror stories towing experiences using 1500/2500 and several 3500 DRW trucks but why bore everyone with BS that has no revelance to a 7800 GVWR trailer and a '12 1500 chevy truck.
I wouldn't add air bags till you make a couple of trips and then make a informed decission if anything is needed.

RE: Baby it's cold outside and wet inside.
We lived in a aluminum frame 5er for one winter with temps down close to zero with 35-40 mpg constant winds. I skirted the trailer and made 1/8" Lexan storm windows that cut the amout of LP usage. We tried the usual cracking vents and windows/two fans running 24/7. It did nothing but make the heater run 24/7 and a cold cold drafty trailer with lots of sweat. Didn't make sense/cents to vent out 75 degree air and pull zero-50 below temps into the unit.
I finally bought two dehumidifiers. This and several containers of DampRid finally got rid of 90 percent of our sweat in the unit.

RE: Eternabond on roof seams
(snip)
I want to prevent the problem before it occurs. I've used Eternabond before, and for a cheesy looking product it sure sticks well and lasts. Maybe such cheese makes a superior sealant.
cute. :R
Never said the product was chessy. Just the chessy job in the pics.

RE: 5th Wheel Tires
A 13000 lb wet trailer ?? With 12168 lbs of capacity tires !!! Keep them pumped to the max sidewall pressure 24/7.
Its after the fact now but is the 13000 lb a estimate or actual scaled axle weight ??
Part of that weight will be on the pin.
Not if the 13000 lb number was gross axle weight.

RE: Tire Load Ratings
Yeah your over thinking your trailers tire issue as many new folks do. A trailers tires are in the center of a tall heavy box that the tires slide sideways around cornors unlike your tow vehicle with tires at the cornors with the front pair steering and the rear pair following around cornors. Two completly different operating invironments.
A 80 psi rated tire on a trailer weighing less than 3000 lbs is not a good move. The benifits of the 80 psi tire comes at those higher pressures. As was mentioned at some point a trailer can have to much tire for best long term reliability.
Sure newbies may point out a minimum pressure tire chart but experience has show us tires used in a trailer position work best at their max pressures.
This from probably the oldest trailer tire maker (Goodyears) tire website;
Goodyear max tire pressures
Special Considerations
Unless trying to resolve poor ride quality problems with an RV trailer, it is recommended that trailer tires be inflated to the pressure indicated on the sidewall of the tire. Trailer tires experience significant lateral (side-to-side) loads due to vehicle sway from uneven roads or passing vehicles. Using the inflation pressure engraved on the sidewall will provide optimum load carrying capacity and minimize heat build-up."
I've found using a tire with a bit of excess capacity (10-15 percent) and ran at its max pressure are much more reliable that a to large capacity/heavy/higher pressure rated tires ran at low pressures. Remember low pressure can cause a tire to run hotter than max pressures and can be a major cause of sway issues.

RE: Eternabond on roof seams
Your going to Eternabond a new '11 camper ?? First contact your trailers dealer/manufacture for their input and read all four pages of this thread.
The trailers and pics I've seen of Eternabond lapped over the tiop edges of the trailer looks pretty cheesy.

RE: flipping axle's
ERS
A 2" x 6" steel tubing is its actual outside measurement. According to which way the tubing was turned the trailer could be raised a full 2" or 6".

RE: Trailer Tire Rotation
I've worn out many sets of tires on my equipment trailers and never rotated them unless the axles were out of alignment or worn suspension parts caused odd wear patterns.
I just ran my last set on the 5er for over 7 years and close to 60k miles. No rotation as they all had a normal wear pattern.
Tires on a multi axle trailer side scrubs around cornors/front to rear load changes running down the road. That keeps the tire wear pretty even.

RE: So whats with all the crew cabs?
My wifes '06 1500 crew cab 4x4 owners manual says "fifth wheel or gooseneck trailering is not recommended for this vehicle". I checked with both of my area GM dealers about the recommendation. They said it was like the no truck camper clause for certain truck configurations.
The truck has been back three times under warranty for the infamous GMs steering half shaft rattle replacement. The dealers service mgr saw the GN hitch and asked how it does with the little short 5' 10" bed. No issues.

RE: 245/75/R16 or 235/85/R16?
If either size has no clearance issues I prefere the narrow 235/85 series tire as the 6.7" tread width closer matches the narrow 6.5" wide trailer wheels.
Many 245/75 series tires can have a 7.5 inch wide tread. High load carrying tires work best with the wheel as close as possible to the tires tread width unlike a high performance vehicle with lightweight tire loads.
Lots of 245/75 tires on std 6.5" trailer wheels so choose the size that works best under your wheel well.

Relax guys, Supercharged is a troll. Look at his posts in his profile and just ignore him.
Is the fee drop just for recreational towing or all haulers ??

RE: Limited slip on Dodge?
Dodge uses a Trac-rite starting with the new '03 a up rear axles. I have been stuck with this unit with one wheel on snow pack and the other on my gravel driveway. The Trac-rite is worthless in that situation as it requires the truck to be rolling before the unit locks the axles together. One great tough unit for leaving two long black strips on hard pavement. This was a hugh issue on DTR and TDR webs in '03 and '04 when the new units came out. In fact the owners manual recommends lightly applying the emergency brake to lock the axles together to get you moving.
The older Dana Trac-lok and GMs G80 is hands down a better locker than my Trac-rite. Very disappointed in Dodge for using this type of locking devise.
This from Dodge; Note the dates...
The following is a S.T.A.R. Center Case Report:
Report created Jan 6 2004
Updated Jan 13 2004
Customer says his trac-rite rear diff is not working?
GCK1: 01/06/2004
Recommendation/Solution
Review AAM Trac-rite diff characteristics. Rear diff is working or truck wouldn't move. It will overrun like standard diff if operating on extreme differernces in surfaces. (Ice under one rear tire with other tire on dry pavement.) No further action.
:GCKI:01/06/2004
The 2003 heavey-duty Ram uses and American Axle helical differential or Trac-Rite. The Trac_Rite differential is different then Trac-Lok in that it uses helical gears (Trac-Lok uses clutches) to transfer power to the opposite wheel when slippage occurs. The transfer of power from wheel to wheel is torque sensitive and must have both wheels spinning (not stationary) to function. It is possible for the Trac-Rite differential to not send power to a wheel if is not spinning. Example: Accelerating from as stop and one wheel is on ice and the other on dry pavement. If accelerating to fast, the wheel on the ice may spin and never send power to the whell on the pavement side. A slower start may be necessary to start the vehicles momentum.
A written test procedure for Trac-Rite is not listed in the repair manual and the following points should be noted:
Testing the Trac-Rite differential while the vehicle is lifted and turning one wheel by hand, the opposite wheel will turn in the opposite direction. This is normal.
If the Trac-Rite assembly has and internal failure it will lock axles 100% side to side.
To test the Trac-Rite process, raise vehicle on appropriate lift, place into gear and accelerate quickly (hard launch). A second technician will witness both wheels turning at the same speed at the start of the acceleration.
Another test for Trac-Rite is to slowly drive vehicle in an open area and completely turn wheels to one direction and accelerate hard.. The vehicle will experience tire hop or shudder. This is normal. Trac-Rite differentials do not require friction modifier and should be used only with SAE75W-90 GL-5 synthetic fluid PN 05102232AA.
The Trac-Rite differential found in the American Axles may look like the helical gears have ground away the case. Six small half circles are noticable on the side of the differential opposite of the ring gear. These openings are desinged for oil flow and are not the result of the helical gears grinding through the differential. Please do not replace the differential case or any other part of the axle due to these openings.
Note: All American Axles require Mopar lube part# 05102232AA synthetic and does not use a friction modifier.

RE: Might as well ban them all
In the latter there would be a sticky on guidelines that explains what information is needed (the make and model number does not help) like:
1. GVWR
2. Number of axles
3. GAWR
4. Tire size and pressure from the placard
5. Current size and weight rating (optional)
Agree 100 percent. The sticky should be for every trailering forum. This would eliminate pages and pages of guessing/misguessing/etc type replies that split off into other topics and directions before the OP reports back 3 days later with a "I don't know what size its in storage".

RE: New Tires For Small TT Heading to Alaska
One downside of using to much tire is when using 65 psi rated tire on that lightweight trailer the tire may ride the center of the tread reducing braking performance and induce sway issues.
Then on the flip side if only 50 psi is used in that 65 psi rated tire it can have sway issues induced by carcass roll which is like pulling a trailer with severally underinflated tires. It wallows all over the road behind the tow vehicle. Underinflated tires = hotter running tires.
I would use a tire with the proper capacity for your trailer and the correct pressure rating determined by the wheels.

RE: Might as well ban them all
That sure was one of the best threads on that subject I've ever read......Too bad we won't get to hear the whole thing from someone with a great amount of knowledge, and with the help of a few of our own here........Thanks Mod.
I would have liked being able to read what he had already posted but I guess that's not possible now.
Its easy to do a google on "Barry Smith and Allexperts" for pages and pages of simuliar Q&A who I assume is CapriRacer. He is very knowledgable in his field has already answered many qusetions on the same topic.
The wise trailer owner should be more interested in what actually works vs what the tire manufacture has to sell and says.
We won't find a better sourse of "experienced" recommendations that actually works on ST vs LT tire topic as we have on this and other RV websites.

Pre game Amercia the beutiful song by Blake and Miranda was fantastic. However the National Anthem was butcherd by Kelly Clarkson IMO. Some may like that type wailing.
Agree the commercial were lame. Probably Beevis and Butthead types enjoyed some of them. Commercial have gotten sophomoric the last few years and it amasing someone actually pays money for them.
