Average gasser fuel mileage

[chasecoffey]

So I've got a 97 hr endeavor le gasser. Ford 460 f53 chassis 38ft tag axle. And I'm wanting everyone's opinion on the average fuel mileage. I've not had the chance to take a trip with it yet but I'm trying to get a estimate of the mpg. Thanks for your response.

Debrey at what highway speed? I've heard people traveling at 60-65 for best mpg.

Around 7, would be my guess.

In our '98 Santara 35' with 460 and tag we got 6 to 7 at the most but we were towing a '95 Honda Odyssey on a dolly.

We've gotten as low as 6.5 climbing a lot of grades, and as high as 10, on a long flat route, with a little tailwind. But for the most part we can count on 8mpg as a rule. I plan on any trip that it costs about .50 per mile when the gas is about $4 a gallon.

If you see more than 7 I'd be surprised.

32 ft allegro no toad 8.5 on highway at 65-70

I'd plan on 6-7 for that first trip, then go from there.

When we had a gasser, a '97 35' Bounder, we got 6.8 at best. With the dash A/C running, we were at or below 6 MPG. YMMV but plan on being on the low side of what you read on these forums.

[dlaughlin]

Almost forgot... The most efficient speed for the 460 is around 2400 RPM if I remember correctly. But someone with more knowledge may be able to correct me.

7mpg running at 60-62mph pulling a Honda CRV

I have a 96 HR vacationer, 454 multi-port inj. Auto/od , 32' no toad. At 65 mph, our first tank was 10 mpg! Second was 9.2! Third was 9.7! I remember when these MH's came out, and they were wind tunnel tested, for fuel milage, and i remembered that when i was looking for a MH. I remember the styling, and though at the time, looked like a guppy! But the style grew on me, and was i surprised when at the fuel island. For our whole trip, we averaged 9.4 mpg. The total mi. were just over 5000. The wind played a big part, and the mountains too. But, i was very pleased with the milage, and was expecting 7 to 8 mpg.
I think, it depends on how you drive, the wind, how heavy you are. With a tag, that tells me you are heavy, so like the others said, 6 to 7, 8 if your lucky! Best of luck!

My old gas coach, a 454 with a carb and 3 speed was 7-7.5 and as low as 6.3 climbing the mountains. My newer ford V-10 is again 7-8 mpg. I plan all trips at 7mpg and $4 a gallon, that usually enough to cover fuel cost for driving and running the generator.
