Real life MPG numbers wanted.

My F350 is a Crew Cab w/ 8' bed, Automatic Transmission, and 4x4 Dually.

99 f250 long bed 4x4 with a Bigfoot 9.6 and it gets 13ish loaded. Thats why I got rid of my Tundra that got 8.6 mpg loaded. It was a screamin little truck empty but it was just over worked. The Ford Powerstroke will pull 70 over Vail pass with the camper but I am sure the fuel milage is about 4 mpg when I do that.
I chose the Bigfoot hard side because it is built like a boat and has no membrane roof to leak, and no mechanism to fail. I have seen that happen before with a pop up truck camper but it could have been owner operator error. You would be amazed at how heavy a pop up camper roof is!!
Fiberglass shell that is easy to clean, no fabric that can flap in the breeze at night and it is insulated.

As others have stated here go for the 1 ton!

I posted a question on the RV.Net site about 6 months ago asking truck camper folks how to increase fuel milage. I wanted to know if anyone had increased their mileage with fuel additives or computer chips etc.... Just about everyone said don't waist your money, just drive 60 mph and that will give you the best results! So on the trip I am currently on, I have been driving 60 mph and I must say, mileage has been good, about 13 (12 -14 range) the entire time! I am loaded heavy too! The best thing about driving 60 is that I can stay in the right lane and the rest of the traffic passes me. It really is a lot more peaceful driving when not trying to pass truckers when I drive 70 or faster. I also see a lot more things from the right lane driving 60 mph. So driving 60 mph gets my vote for the best way to improve mileage, see more and have a lower stress trip! When I need the extra power to pass someone or merge to the left, my big diesel named "Bertha" has the power. I wouldn't go back to a smaller gas truck no mater the size or weight of my truck campers in the future!

Not exactly what you're asking for, but FWIW:

2000 GMC Sierra 2500 (3/4 ton), 6.0L gas V8, 4L80E (4-spd) automatic transmission, 4WD, extended cab, longbed, stock suspension, 245/75/16 wheels/tires (stock size), no heavy add-ons (i.e. stock bumpers, no winch), with Northstar TC800 pop-up camper (8-foot length, fits entirely within bed, but tailgate must come off). Most of the time when traveling, there is a large 4-bike rack on the rear hitch, with 2 to 4 bikes on it -- not sure how much this matters in terms of MPG on this truck though.

Real world MPG at 65mph max: 12 hwy, hand-calculated. I've seen 12.5 (slower highways, 55mph), and occasionally 11.5 (higher speeds, say 70-75), but almost all of the time it's right around 12 mpg. Truck has plenty of power, but I try to go easy on the accelerator to keep the MPG as good as possible.

Hey Kevin

What kind of mileage are you getting with your Tundra and pop up? That's the route I'm planning on going. Wanna take my kid to the National Parks and camping all over the place.

Thanks guys, keep em coming.
Any more gassers out there?

Dieselandmud, what are you doing to get that mileage, thats what I'm shooting for!
@ Oni - I get 13ish with the camper on. I'm going to sell it, if your interested PM me.
