Enjoy your new camper!
Ps -buy the supercharger!


Oh man....the Eco Boost Toyota, lol. Seriously I heard those things are a beast. I have a 2010 5.7 4x4 myself but they said you can't put those in 4x4s for some reason. WHen I bought my truck I inquired...they said it would be like 7k to add it but then were like oh wait you have a 4x4 so you can't. I would not have done it then but now that I have my TT it would love the extra power...but really I don't need it for what I have. At the same time I'd rather have more than I need of just about anything.

It's amazing how that adds like 130HP to an already pretty beefy 1/2 ton.

I really love my Tundra but on my very limited towing since I've got my TT I'm not getting anywhere close to the MPG you are getting. I'm getting like 8 I bet. I went like 85 miles on almost a half tank. I need to reset the computer to track the MPG when I tow to really see.


The supercharger can go on any configuration 4x4 or 4x2. They can't be installed on a "flex-fuel" model though.

The thing about towing in the mountains that no one has mentioned yet, particularly the Rockies with their MUCH higher altitudes than the Smokies is that a naturally aspirated motor (non-turbo diesel) will lose from 3-5% of power per 1000' of altitude... Some passes in the Rockies are near or over 12,000' (Loveland Pass = 11,990', Independence Pass = 12,103') so your 5.7L motor could be down in power as much as 60% when crossing a 12,000' pass...

I towed Loveland pass 2 years ago with my truck and trailer and I was down to 20MPH in 1st gear crossing Loveland with my #9400 TT, and that was with my modified V10 making 360 HP and 500 lb ft of torque!!! Your TT could gross as much as 11,137 pounds if loaded to max GVWR and you have significantly less motor than I do...

IMO, too much trailer for too little truck - Rocky Mountains or not...

Something I have always wondered is how often a TT is loaded to gvwr? I suppose it is easy to do is you TT only has about 1000lbs of payload but for several the payload capacity is simply huge.

I know and fully understand that using the gvwr on the TT is a good rule of thumb for figuring the most the tongue weight would ever be, but does this lead to people over-estimating the tongue weight?

For instance, my Layton is dry at 4970 lbs and a gross of 7700 lbs. that's 2730 lbs.

My tongue weight dry should be 745.5 lbs
Gvwr is 1155 lbs

My estimate is 6000-6500 ready to camp. Estimated tongue weight ready to camp is 900-975 lbs

All figures using the .15% rule.

Using the gvwr I should have 1200 lb wd bars, but I have 1000 lb bars and they seem appropriate for my estimated weight of 6500 lbs.

Now under wd the effective weight transferred back to the travel trailer is around 250-300 lbs . So the effective load added to my truck is around 700 lbs or so.

I am not suggesting that someone overload a hitch or be unsafe. I just wonder how many of these half tons have much less load on them than we suppose with the effects of wd and the fact that TT are not always loaded to gvwr. (but I am sure there are TT that are overloaded just like their are trucks overloaded.

Anyway. I am tired and just musing.

I am going to put it on a scale and figure out what really gives for my rig.

Itm planning to pull it to Fort Wilderness at Disney over the summer. I suspect that the rig will do just fine.

I was checking out this thread because I really like the tundra and would own one if I could afford it.

Thanks

Yep...that must me it...I have a flex-fuel. I've used the E85 with it like twice...it give terrible MPG to the extent that the minor savings you get at the pump are totally not worth it.

I'm not sure if you are just saying you can't afford a new truck or are saying that Tundra's are more expensive. When I got mine I really compared close with other trucks and based on the options I was wanting the Tundra was really no more expensive and in some cases less expensive. All car makers have fluff packages that can really make the costs skyrocket.
