Full timed for 10 years and pulled a 34' AS with a Ford F-350 7.3 Powerstroke diesel crew cab dually with 4:10 rear end. Truck bed was my garage and basement. Fully loaded weighed in at 19,000 yet met all load restrictions. Averaged 12.5 mpg over the ten years. If that was a gas job would get about 8 mpg. Hooked up we were 58 feet long and had no problem maneuvering in Yellowstone.

The question is not about pulling power or miles per gallon, it's about stopping power. The one-ton has bigger brake shoes and pads than a 1/2 or 3/4 ton. If MPG is your major concern than go light weight but make sure it can stop the load you are hauling. We've all seen the big fifths being pulled by a 1/2 ton knowing that stopping ability is limited. That's scary.

If you are doing a lot of traveling, go diesel. Better mileage, less maintenance.

Good Luck.

Tow Vehicle vs. MPG

08 Silverado,
5.3 L
3.73 axle
4X4 "heavy half ton"
31' Sovereign, 6,500 lbs

Fuel mileage is 9 to 11 depending on how I drive. 60 or under I get 11.

The truck will pull hills like Texas Canyon and Ranger Hill at 70 plus MPH, which means it runs roughshod over 98% of big trucks.

Climbing an 8% grade south of Globe AZ we dropped to 35 MPH, but would accelerate if I kicked it down to first gear, but I didn't do this except for a very brief test. I imagine I could have pulled this at 45 if I would have been in a big hurry.

I have no issue with tongue weight, and don't run an equalizer.

The rig stops very well with functioning trailer brakes.

The old 7.3 was a good reliable engine, the later offerings from Ford and Chevrolet,,, not so much IMO.

We are traveling through Calif right now, a variety of temperatures, winds, and altitudes. We tow the same trailer as you, fully optioned, returning home after a 6 month trip with extra weight of purchases of purchases. Our truck is a 2012 Ram Express 1500 Hemi 5.7 Reg cab 120" wheelbase. The hitch is a 1400# ProPride.

We average about 12 mpg towing, more or less with wind, speed and hills and 20-21 not towing using regular gasoline (less expensive than diesel).

Yesterday we stopped at a scale to get our fully loaded travel weight (with souvenirs) hooked to the tow vehicle. Steer axle 2960, drive axle 3380, trailer axles 6520, gross weight 12860. All within limits. Weight distribution set so trailer and truck level.

The trailer, truck, and hitch combination handle beautifully in wind, heavy semi traffic. No driver stress whatsoever. I use tow/haul mode and transmission in 4th gear giving 2100 rpm at 55 mph so there is no downshifting on normal grade changes and wind conditions. I shift down as need to climb or descend steep grades without using brakes.

Steep climbs at 90 degree temps yesterday gave 227 degree F oil temp peak, 223 water temp, and 178 transmission temp.

It's a nice, economical to purchase and operate combination, not sure what more we could ask. Don't underestimate the comfort of towing with a Hensley/ProPride style hitch, that's a big deal here that makes this work so well.

Thanks all, Hobo

I'm under the impression that in-bed fuel tanks are for diesel only.

Oh, should mention the Ram has all disc brakes, the trailer stock drum brakes (discs can be added but not needed unless traveling long, steep grades routinely and fast), and it stops the medium sized trailer and relatively light weight truck with ease.

I can't imagine why you would want an in-bed fuel tank. You will have to stop to leak before you will ever run out of gas.

Be careful not to get caught up in the quest for the truck/trailer that can do everything but none of them well.

There is a huge advantage to having an extra fuel tanl

I carried 65 gallons in a 1973 Buick.

Why?

If you need to visit the bathroom, stop and go into the trailer your hauling.

The other huge reasons are if you tow late at night, many gas stations are closed.

And the best reason, is you can avoid paying ridiculous fuel prices by avoiding the need to refuel, in states like California.

I had a 2008 Chevy 1/2 ton 3.73 4x4 that got the same to worse towing mpg as my 2012 Chevy 2500 gas engine 3.73 4x4. (8.5 to 9 mpg over many miles of towing). My truck's role in life is to tow my 25 foot Airstream. The diesel is more than I need and the 1/2 ton is less than need because of payload capacity.

I don't think you can buy an in-bed aux gas tank. I looked at that when I had a 25 gal tank and could not find one. Present truck has 36 gal tank which works out good.

In bed fuel tanks can easily be added.

The harder part is to have the change over valve installed near the driver..

A word of caution though.

There is usually a return line to the regular fuel tank.

Therefore it's essential that you burn off some fuel from the regular tank, so that the returning fuel does not over fill the regular tank when using the spare tank. Then watch the regular fuel gauge increase as you continue with your trip. This prevents the spare tank fuel from over filling the regular tank which then simply dumps it over board.

Axle rating on 25 foot trailer

About what Andy R. said above....My 2013 25FB Flying Cloud came from the factory with 3800 pound axles. I don't have any explanation why they would provide axles that heavy (As others have mentioned above, the trailer's published GVWR is 7300 pounds).

(On the main topic, I tow with an SUV, not a pickup. I get about 11 MPG.)

Having had an in bed fuel tank for years I can't imagine not having one.
I can drain myself behind a tree but not likely to find fuel there

I chose a 3/4 ton super duty over the 1/2 ton F150 purely for extra payload. The 150 can pull my 7500lb trailer but I wanted more than a few hundred pounds carrying capacity. I have a thirsty V10 that gets anywhere from 7-10 towing depending on grade and headwind but I can climb any mountain. I replaced the 29 gallon stock fuel tank with a 47 gallon from Transfer Flow. Best investment I ever made as I can now travel up to 400 miles between fill ups and like Andy said, get out of California without having to fill up at high prices.

depending on what you carry the weight thing can creep up on you.
In my case the truck is a 13 ram crew cab, long bed 4x4 diesel which is pretty heavy to begin with .
Add an aluminum cap, 50 gallons of extra fuel,2 people, all the usual chairs barbecue etc. and way to many tools and it weighs in at 9300 lbs before I hook up the trailer so that does not leave a great deal of leeway at a 10k GVW rating.
Admittedly overkill with a 5000lb trailer but it did deliver 15 mpg plus (hand calc.) on our recent 3000 trip. Almost all towing. I have not driven it solo enough to accurately determine the mileage.
We may put to much emphasis on the MPG thing. At $4.00 a gal. the difference between 14 and 15 is $20.00 per thousand miles
