My guess (could be wrong, often am) is that you aren't getting a whole lot more that 15-16 just driving around empty in a 5.7 Tundra... You might be hard pressed to get 15 towing even a pop-up.

Lighter weight and low profile trailer will help some however...

Unless you are going to be towing much more than camping I would not buy an RV based on potential better gas mileage. Do the math. With gas at 3.50 per gallon and 10 mpg it costs 35 cents per mile. At 12 mpg it costs 28 cents per mile or 20% better. If you take a 500 mile trip the difference in fuel cost is $175 vs $140 or $35. Compare that to the cost of a new camper, etc.

When I was towing a 2500 lb. pop up trailer with my Mazda B4000 I got 15 or 16 MPG towing and 19 or 20 running empty. Don't know if this helps much or not but that's about as good as I can do [emoticon] I would expect you'd find something similar (loosing something like four or five MPG towing depending on the actual weight.
Good luck / Skip

You said a large popup, so probably one of the heavier ones. I would guess that you'd get 12 or 13 (maybe 14). But by the time you sell one and buy another (and take the usual beating), it will be hard to recoup the loss in saved gas. You bought your present trailer for a reason: presumably you like the layout and enjoy using it. Will you enjoy a popup just as much? Even after you have to crank it up and do all the setup on a really hot day, or after you take it back down in the rain? I don't know how many miles you'd tow in a year, but you're only going to save about $150 or so per 1000 miles by downsizing.

I had a small Starlite popup... for one summer. Did not like it. Got about 14 mpg towing with a Windstar van. Then we got the Mountaineer (like Explorer) so I was able to tow something larger, and I bought a 2304s like yours... got 9 to 11, mostly 10 mpg. Had to sell it due to wife's medical bills and condition. Since she stopped camping and I still wanted to go, a few years later I found a used 17' Burro... 14 mpg with that and my Highlander, thanks mainly to the rounded shape of the Burro. Now getting 12 mpg with the current rig. I looked at, and figure I could have hit maybe 17 or 18 mpg with, a Rockwood A frame folding trailer; but I feel it is worth the extra expense to have the ability to pull over and walk right into the TT to use the bathroom or fix a sandwich. And I tow the TT 3K-4K miles each summer.

I have a 2006 F150 SuperCrew 4x4, 5.4L, 3.73:1 gears. I typically get 16-17.5 mpg empty. 12-14 mpg with our 2009 Jayco 14HW (4200-4300 lbs ready to camp). All of this is with max speeds of 60-65 mph. Crank it up to 70 mph and it struggles to get 15.5 - 16 mpg empty. Towing my baja bug on a uhaul car hauler I got about 8-10 mpg.

I have an '07 Tundra with the 5.7L V8. I have a Starcraft 11R/T "Offroad" PUP that is 19' long and runs right about full 3,500# GVR when I have my gear loaded in it and the PU bed. With 2 of us I get between 12 - 14, depending on which direction I am going over the Sierra's.

I drove down to LA from the Bay Area & picked up an Eclipse Milan 18CK travel trailer and towed it back to San Rafael, CA. I was getting 17 - 17.5 on I5 going down at 70 - 75 mph. Comming back at about 60 mph average I saw between 9-11, with substantially less (7-8) going over the Grapevine. The milleage was significanly lower than I am used to with the PUP.

Similar to Fairfax Jim's comment, my 2004 Tundra with 4.7L V8 I get 14-15 mpg when towing my pop-up. Empty is only slightly better at 15.5 mpg average.

I have a 2010 Ram 1500 Quad Cab with the Hemi (also a 5.7) and tow one of the heaviest pop ups made. It's a Niagara 14ft box High Wall pop up that weighs just under 3,200 lbs dry.

Not towing I get around 14 mpg driving in town and 20 mpg on the highway, and even when not towing I don't drive above 65mph.

I get anywhere between 14.5 mpg to 17 mpg towing the pop up depending on headwind or tailwind and if I am towing in higher elevations . I tow no faster than 65 mph on the highway and I have a Truxedo TruXport Tonneau bed cover on the truck.


Now I also live in South Texas where it is pretty much flat, and those higher elevations we go camping at in Central Texas are refered to as the "Hill Country" here. The highest point being only 2,400 ft which is as close to a mountain as you're gonna get in TX unless you go 400 miles further to the west at Big Bend National Park in TX which borders Mexico and has mountain peaks above 8,000 ft.

A good ballpark figure based my experience and other posts,is if you tow a popup expect a 20% reduction in MPG from driving empty,and a 40% reduction when towing a travel trailer.
