The problem is that it is a range from 15% to 25%. Mine is right at the low end at 15-16%. Others will be at the high end. Depends on the configuration, tank location and how you load it. For example, if you take a 10k GVW trailer, the pin weight might be 1500 to 2500 lbs. Quite a range. You really have to know the pin weight% for the trailer you are looking at.

In general, the pin weight% will stay the same loaded as unloaded (probably not for Toy Haulers). Calculate the dry weight or shipping weight pin% and apply it to the GVWR. This will get you very close to a maximum pin weight.


I agree with everything quoted.

Sunny,

I tow right at 21%, can't say as I've noticed any particular
problems with towing/stopping/porpoising. I am a bit over on
GVWR (9200 #), but not on RAWR,FAWR,GCWR. Many discussions on
here as to weight related issues. With my configuration, I am satisfied with
the way my 5ver handles. I have not taken my rig off-road.

BTW :Factory Dry pin wt. : 2315 #'s. (or 20% +/- of Factory
dry wt. 5ver : 11,245# )

20% of what weight? because the trailer is bound to weight more then the 'brochure'. my pin weight was supposed to be 2800# roughly, turned out to be 4044 # according to a cat scale.
Where are the axles? how do you load (frontly or balanced) ?

Good point. I've been using 20% and 25% of the GVWR.

The more the pin weight the better the trailer will tow provided the TV is able to handle the pin weight.

Not really true at all.

Apologies for the confusion... I did my pin weight
calculations on what I run loaded ready to go camping for a week.

If I used the factory GVWR on my fiver (14,300 #) my current pin
weight (of 2600#'s at the Cat scale) would be between 18-19 %.

I do not plan to run at 5ver GWVR with my current tow vehicle. That
is why I was more interested in the weight calculations I actually tow .
The factory data indicates a "max." pin weight of 3000 lbs.

Good luck... hope you can avoid numbers mesmerization.

What trailer do you have that states a max pin weight? I have never seen that. Chris

Chris,

Not a max pin weight for the fiver, a max pin weight listed
for the tow vehicle in my sig. block. 3000 #.

Here is some data on our trailer:

Advertised weights:
Dry Weight - 9761 lbs
Hitch weight - 1942
Axle weight - 7819.
Factory dry weight - after factory options - 10,015 lbs
Axles rated at 5200 lbs each.
Length - 33' 11"

Truck weight is about 8050 lbs with me in it - 3/4 tank of fuel and hitch in truck

CAT scale
Steer Axle - 4900 lbs
Drive Axle - 6060 lbs
Trailer Axle - 9220 lbs
Gross Weight - 20,180 lbs

2 passengers in the truck, full tank of diesel (36 gallons) and 1 small dog. Trailer is "packed" for 2 weeks of camping and about 1/3 tank of water.

Add on’s to the original weight - Both propane tanks full, additional 12V battery and 3 slide awnings.

Glad I purchased a 3500HD diesel truck to pull the rig. Our truck GVWR rating is 11,600 lbs.

Don't short change yourself on the Truck. While a 250/2500 may work for the 5er you're looking at now, if in a few years you decide to go bigger you'll be looking for a new TV for the bigger RV. We were only looking for a 2500 a few years ago, but couldn't find what we wanted, but the Dealer had a 3500 Diesel Dually with all the options we wanted and for a better price than ordering a 2500. Didn't need that big a TV at the time, but when we decided to move up to a 5er we weren't limited by our TV. Just something to think about since you don't have a TV yet.


Same thing happened to me. Went to the dealer in 2004 looking for a 2500, pretty well set on diesel power, but nothing that really pleased us. Found the 3500 in the color combo and equipped the way we wanted it, and invoice/sticker was only a couple hundred bucks more. While it was more than we needed for our previous TT (23' Komfort), glad we got the 3500 as it is needed for our current 5'er. I'm sure we will replace this TV in a couple years and replace it with a similar truck, albeit newer with higher tow and weight capacity ratings.
