    Just took our travel trailer on its maiden voyage and was blown away at how horrible the mileage was. I expected bad, maybe somewhere between 9 to 11 but I got 7mpg?!

    I'm towing with a 2011 Taco DC LB 4x4 with a Leer camper shell. Our travel trailer is 19ft and 4500lbs loaded. Trip was on flat ground, no wind and stayed around 60 and never went above 65. Aired all the tires up to 37psi before we left and stayed in 4rth gear (automatic)

    I read alot of posts on here before we bought our trailer and it seemed, even the guys that were towing 24ft++ trailers, were getting somewhere above 9mpg. Am I missing something? Was planning on towing the truck up the Sierras and doing some camping in the mountains at Tahoe this year but I'm having second thoughts now.

    What do you guys think!?

    Heaviest trim level truck. Camper shell. 4500lb trailer. Highway speeds one ratio down from top gear.

    Where's the surprise?

    Just because I don't think I've ever heard anyone admit to actually getting 7mpg. I have freinds with full size trucks and Class A gasoine RV's that get better gas mileage. I figured at worst I would be getting the same mpg as them, but not any worse

    I'd bet you would have been closer to 10 if you were in 5th.

    I know it locks in both 4th and 5th, but I was reading in Popular Mechanics, and they statted that it can also achieve "partial lock" in 3rd. Most TC's lock either On or Off, where as the one on the Tacoma can have varying degrees of lock.....However, aside from that article, I havent found anything else to back that up. Everytime I have the opertunity to test this in my truck, I forget.

    so you guys think it would be ok towing in D as long as its the tranny isn't hunting? I know everyone has their own opinions but I thought the general consensus was never tow in D. I'll have to do some experimenting...


    About how much do shells weigh anyway? We got the shell to camp in the back but have a newborn now (reason we upgraded to trailer) so no need for it anymore. Might help the mpg a little (realistically maybe 1/8mpg) =)

    Thanks for the responses! I'll keep tweaking and see what I come up with. There is def a learning curve with rv's and went pretty well for our first weekend until we packed up camp drove off and 20miles down the road I remembered I left my full cup of coffee in the microwave! made a mess but was good for a good laugh!

    Not towing in Over Drive or the 5th gear in our Tacoma, is a thing started back in the 70's, as the OD gears were a very weak planetary gear set. Now, there is no issue towing in "D", and letting the tranny do its thing.

    Im not really even sure when i "need" to use overdrive, or when it would be useful, the tranny downshifts whenever it needs to

    If you do come up & want to hit a trail with some fellow TWers give us some advance notice and we can probably set up a run. http://www.tacomaworld.com/forum/south-west/167767-reno-sparks-trail-run.html
