3 mpg seems a bit much to lose. From 12 down to 9 mpg is 25%. I think speed, wind, terrain might also be an issue. See how next trip goes.
Who gets 12 mpg towing almost 10,000 with a gasoline fueled tow vehicle? "gets less gas mileage by about 3 mpg". Probably lucky to get 8 mpg which resulted in 5 for the travel trailer. Since we don't know the route or even the average speed, simply saying 40% less gas mileage is meaningless.
We still don't know the numbers or how it was calculated.

12 is high? Sure. Say it was 9 and dropped by 3 to 6 mpg. That is a 33% drop. Seems high percentage for like conditions.

No you didn't. Maybe once, going downhill from the gas station... unless you have one of those super carburetors the govt tried to destroy...

I pulled a 24' TT, a 30' TT, and a 35' Fifthwheel all with the same truck, a 2005 Chevy Extended Cab Dually with the Duramax and got almost the same mileage with all three, at least not enough difference that you could really tell.

When we went from our S&S truck camper to our first 5th wheel, there was no difference in mileage. I honestly did expect mileage to get a little worse, but there was no change. There was a large weight difference, but not as much in aerodynamics.

hornet28,

Yes, A 5th wheel has a considerably better aerodynamics flow being a continuous surface for air flow than a TT which is located behind the tow vehicle and thus the flow is disrupted along the surfaces.

BTW, perhaps your brother and his wife each drove Ford diesel trucks and kept a trailer down at Old Town Campground n Retreat at Old Town FL where they'd stay at in the winter often between RV hauling trips back when Joe and Linda owned the CG. They lived in Muskegon. Had your Bro passed several years ago and his wife still hauled RV's for a few years and later had a smaller trailer at the CG? We live in Grand Haven about 13 miles south of Muskegon and have been going to Old Town CG for about 10 or so years now for about 2-1/2 months in winter. Just wondering.

Wow Steve...that is terrific mpg towing a 14K FW! I'm not sure my gas 6.2 will get 16.5 mpg running empty? Maybe on a still day at 55 mph.

Jerry


that is Canadian gallon and a modern diesel truck. empty I get 21 to 24 mpg depending how I drive.

Well seeing how a Canadian (Imperial) gallon equals 1.201 US gallons, while 16.5 mpg is good it needs to be reduced by at least 20%.

We just sold our 2011 Crossroad Cruiser Patriot 5th wheel for a 2020 Winnebago Voyage travel trailer. The 5th wheel was 34 foot and weighted 9700 pounds. The new Winnebago is 36 foot and is 1500 pounds less at 8200 pounds. The question is the t re mailer gets less gas mileage by about 3 mpg that the taller heavier 5th wheel. Both pulled by same truck .My thought is the weight distribution and pulling of hitches? Any thoughts?


Back in the day I went from a tag toyhauler to a conventional 5ver. 5ver was longer (by like 7') and was taller than the toyhauler. I got at least 3mpg better going to the bigger & taller 5ver. I also was able to crest many hills in a higher gear than I could with the tag behind trailer.

We sold our 33ft 5th wheel and purchased a 33 ft. TT. Expected our MPG's to improve with the lower, lighter TT, but it didn't. Towed each trailer more than 10,000 mi. TV was a '16 Ram 3500 Cummins SRW SB.

33 ft. 5th wheel. 12,500 lbs. loaded. 13.5 ft. high: ~11.2 MPG's.
33 ft. TT. 10,000 lbs. loaded. 12 ft. high: ~10.5 MPG's.

Typically towed at 60-65 mph.
