My guess would be approx 8 MPG. You need to provide a little more information. Engine make and size, length and weight of coach would be helpful.

If all is running well, figure on 7 mpg. If you run at speeds over 65 mph it could be lower.
If running at 55 - 60 mph it could be better.
CC..... Happy Rving!!

If you're definietly going on that trip now's not the time to worry about how much gas you'll be using. If you need gas you're going to have to buy it. Have a good trip!

With our 1998 35' Santara W/460 I could get between 4 and 6 mpg towing an older Odyssey on a dolly.

MPG experience

6.5 mpg @ 65 mph. drop about 1/2 mpg for 10 mph headwind, add same for a tailwind. 8.1 L Workhorse flat towing a 3500# Subaru. You will never get the mpg back on the downhill. Entropy.
As important, check your oil everyday. Good travels

Estimate mpg lowish, divide into total distance estimate, multiply by estimated price per gallon for fuel, and that will give you an idea.

For instance, we took a trip last year about 1,250 plus mi one way, times two, 2500 or so miles total at 8-9 mpg and diesel at about $4 plus per gallon. Fuel cost estimate was close to actual at about $1,200 spent on fuel for round trip.

I'm assuming you have a gasser....maybe a 454. I just spent time on the Oregon coast with a trip down and back on I5. I set the cruise control at 57ish and got just a tick under 8mpg. Pretty easy to figure out how much fuel you'll need if you know the total mileage of the trip.

The way I figure it (when gas is around $4 a gallon) is it will cost you whatever the one way mileage is. For example we drove to Washington this summer and our destination was 1200 miles one way and we spent about $1200 in gas round trip. We get on average 8 mpg, if you drive in your rigs sweet spot you get the best mileage, ours is right around 60mph depending on the terrain. So if you plan on .50 cents per mile you will be in the ballpark and may save a little now that the gas prices are below $4 a gallon. Also no more hotel rooms, so if you plan it right it will probably cost you no more than if you had to stay in hotels every night, and eat out all the time....Have a Fun and Safe trip.
