Looking at maybe changing my setup with a newer vehicle and better fuel mileage. So what kind truck are you driving with your ATC/FWC and what kind of fuel mileage are you getting? Is it gas or diesel? We probably all agree fuel prices suck!

I get about 17 mpg without the camper,and about 14 with the camper on. ANY headwind at all drives it way down. I did a check on one tank with a stiff headwind, maybe 20 k's on the nose, and I was around 10mpg:eek:, and I only had the headwind for a little over half the tank.

I drive a '02 V8 Tundra 4x4.

I have an 07 F350 with the 6.0 PSD and carry a ATC Couger fulll time. In town I average about 12.5 mpg and on my last trip through Yosemite and the Eastern Sierras I averaged 17.2 mpg for the entire trip. I have found that the sweet spot for my rig is 60-65 mph.

We get 16 to 18 mpg with our Tacoma w/Eagle. It has the 4 cyl engine and we installed a fairing on the cab.

I got 18 on my last 500 mile outing which was about 70% on the fwy at 70mph. I plan on slowing down on the next run to see if I can do a little better. I haven't checked it in the city yet. - Dodge 2500 4x4 diesel with Grandby.

[5 Speed]

I have a Tundra 4x4 access cab with a 5 speed manual V-6. I would say speed that has more to do with mpg than just what type of vehicle. I drove the truck camper for 4 months and over 20K and what I found was that if I kept it 55mph and under that I got 20 mpg traveling the whole time. I was going to and in Alaska so this was about as fast as I could go safely. I was loaded and one time about 1000lbs over gvw, not something I am proud of but I thought I could go up to each axle max weight, didn't realize until later that the combined cant go over gvw. Found a scale in Canada and with the conversion of Kg to lbs plus could only weigh each axle I was a little slow. Now I know you all would probably go crazy going 55 but I went 502.4 miles on one tank on about half paved half dirt roads. Deadhorse to Fairbanks with a single tank, probably could have gone farther but didn't feel safe where I would have run out of gas. Now when I drive 65-70 the mpg starts to drop to 16 and with a headwind or speed at 70 it will drop even lower. I find it interesting to watch my scan gauge and you will see the sweet spot for mpg

I just returned from driving from New York state on a 800 mile trip. On the highway I got an average of 22mpg best tank was 24 mpg. This is with a 2004 Nissan Frontier 2.4L 4cyl manual truck and a '07 ATC Bobcat shell kept light. The truck gets 27mpg unloaded. I haven't calculated city mileage. Something that helped mileage was maxing out my tire pressures on the road (44psi front and back). Also, I don't use my ac most of the time, just open the windows slightly. I also drive 60-65mph.

I can get as much as 18 mpg with my Chevrolet 2500HD diesel on level ground at highway speeds while carrying my Hawk. Once I hit the more interesting roads (i.e. back roads, mountain roads, or dirt roads) the MPG drops to 16 or even 14. I record detailed numbers. My best tank was 17.8 MPG over 311.7 miles with an average speed of 54 MPH, my worst was 13 MPG over 97.7 miles with an average speed of 32 MPH.

My '99 Dodge Ram 4x4 w/360 CID (5.9L) engine carrying the same Hawk came to an average or 11.7 MPG, the best tank being 12.9 MPG over 238 miles at an average speed of 52 MPH, the worst tank was 6.6 MPG over 24.9 miles with an average speed of 24.9 MPH. That particular tank of gas was consumed going up and coming back down a road so steep that I used 4x4 low range just to get there and to keep my truck from running away from me on the way back. The second worst MPG I got was 8.7 over 82.8 miles with an average speed of 30.9 MPH. Unfortunately, I didn't make any notes about the driving conditions I encountered on that particular tank of gas.

CK - is your Sportsmobile a diesel?

Marc - How has that 6.0 diesel engine been for you? I have read a lot of horror stories about the earlier version of that engine and am wondering if they have worked the kinks out.
