Unhappy Tow vehicle Gas Mileage ???????

We have just purchased a 25 Foot Safari (about 5k lbs). We have a 2002 F250 Turbo Diesel 4x4. Would a 3/4 ton Suburban with the 6.0 ltr enging pull this rig adequately and what kind of mileage could I expect. We think we would get 12 mpg with the Ford. The F250 has plenty of torque but not so great mileage.

I tow a 25ft Tradewind with a 1/2 ton Suburban. It's 5.7l is adequate for this old trailer. I get between 10 and 12mpg towing.
The newer Suburbans have much better power, and assuming you get the towpackage with the 6.0 in the 2500, you should be getting similar mileage, like the Ford gives you.
Don't expect mileage miracles when towing. It requires huge amounts of energy to move a truck/trailer combination.
Your turbo diesel will be beneficial at altitude, where all normally aspirated gas engines gasp for air.

My 34' weighs in at 9,300 pounds. After 10,500 total miles ... including 1,670 miles of towing ... I am averaging 13.78 MPG.

I would expect 10 - 12 mpg with the Suburban. If a 4X4, closer to the 10. All other things being equal, an '02 Ford diesel ought to tow that size coach at 13 - 14 mpg, with much better torque, and more horsepower at far lower rpms.

A 25' Safari is going to weigh much closer to 6,000 lbs. than 5,000 once loaded for a typical family.

Currently Diesel fuel is about 30 cents a gallon cheaper here than gas. 12mpg @1.59/gal is better than 12 mpg@1.87/gal.

I get 20 mpg solo and about 17 average mixed in-town and highway commuting.

I have a 3/4 ton 03 Suburban with the 6.0 engine and a 25 ft Airstream (about 6,000 lb). Most of my towing is in the mountains and I average between 11 - 12 mpg. I tow in 3rd gear, 55 - 60 mph.

Gas Mileage

I got 13 mpg on 700 mile trip. Mostly flat country at 65mph. 29' AS pulled by 2004 Durmax under 3,000 miles on it so still being broken in.

Stick with the diesel Ford, Our truck and trailer weight, is just under 14,000 lbs. combined, currently 15 mpg @ 65 mph.With a few engine mods, gives us more than enough torque to stay in the fast lane on long grades, without having to fall in behind that slow crawl in the slow lane.

A friend with a 2002 Suburban 2500 4x4 with the 6.0 gets 9-10 MPG towing a 1953 Flying Cloud (22' and guessing 3300 lbs), and she said she doesn't get much better than that around town with no trailer. We get about 13-15 MPG towing either our 31' Sovereign or our 24' Tradwind with our '01 F250 PSD 4x4 at 70 MPH.

I've got a 99 Tahoe 2 door 4x4, 5.7L 350 w/ 3.43 rear end that with a K&N filter gets 16mpg. While towing my 64 Tradewind, 8mpg! I think I'm driving too fast as well as the 250 HP is maxxed out with the tow weight.

You will never touch the MPG that powerstroke gets with anything gas. My buddy took his 02 Crew short bed powerstroke F250 to Alaska last year with a 39ft 5th whell camper toy hauler behind it and in the plains he was getting 15mpg. My pre OD 454 Burb gets 10.5 with a car on trailer weighting about 5600lb.
Her gets 20mpg empty. My burb gets 11.5 empty at best. Grocery hopping my wife has been doing it gets 9mpg.

My next tow vehicle will hopefully be a 4x4 SD 250 crew shortbed with Powerstroke.
