55 gallons, usually go 400 miles between fill-ups.

100 gallons, average between 7.5 and 8 MPG (have been as low as 7 in mountains). I get to about a third of tank when I am around 500-525 miles and am gassing up at this point. When I take trips I plan my gas stops and the longest I will go is in the 500-525 range for my own sense of mental comfort. Gives me a chance to stretch my legs, wife to walk dogs, and switch drivers.

80 gallons, usually fill up around 300 miles. Don't think pushing would be fun.

We have a 150 gal tank. I travel 300 miles max per day and have a half tank at the end of the 2nd day. We fill up the following travel day morning and continue on.

I am looking at diesel coach which gets 10-11gal but only has a 52 gal tank.

I would be very cautious about the truth of that mileage unless the rig is small. My diesel has a 100 gallon tank, and we try to fill up at 1/2-1/3 of a tank. We have averaged 8-8.5 with a 32,000 pound coach with a 6.7L 360 hp engine with a 5200 pound toad.

6-7 mpg
Depends on hills and mountains
In Montana on I90 about 6.2
Flat in Iowa, Illinois about 7.6

It is 30 footer. We have decided against this rig for other reasons though (not this).

150 gallons, normally 7-7.5 mpg, or a bit over 1,000 miles. However, I plan at 6mpg to account for generator and AquaHot use and to add a safety factor. So overall planning range is 900 miles, but I'd not want to drop below 1/4 tank, so that drops it to 675 miles. The most we've ever put into the tank was about 90 gallons.

Thanks,

75 gal, 6.5 mpg towing. I run the Genny for Ac when its hot, 3/4 gal per hr. Genny won't run with less than 1/4 tank.
I try to gas up in 300-350 miles.

I replaced the factory tank (34gal) with an S&B 60 gal tank. I get between 7-11 mpg pulling a 5th wheel depending on terrain. Mountains are tough on the mileage. I start looking when the indicator says 150 miles remaining. Based on range, this upgrade was a great investment.

100 gallons, I think. No idea what kind of mileage I get. Can't think of a good reason to study it. Maybe someone here can tell me how wrong-headed that is!

BillJinOR · 08-27-2021, 06:15 AM

150 gallons 6.7 avg. depending on fuel prices in the area I’m traveling too I normally go 2 days and fill. About 700 miles tops . The most I’ve ever put in over 60,000 miles I’ve had this rig was 115 gallon so I have a large reserve at 1/4 tank that the gauge doesn’t show.

mlh2013 · 08-27-2021, 06:30 AM

128 gal tank average 8 mpg.

tnedator · 08-27-2021, 06:35 AM

100 gallons, 60-75 useful, as I try and fill up by 3/8 of a tank, 1/4 at the lowest. About 6.5 MPG towing (that's what computer says, haven't manually checked in a while and can't remember how different it was).

So, my range is 400-480 miles, give or take.
