I'm right on the brink of acquiring a really nice 1990 Pace Arrow with the Ford 460 and overdrive transmission. I've owned trucks with those motors in the past, liked the power, hated the mpg. Anyone know what I could expect from the Pace Arrow 30 foot with that engine combo? Thanks in advance

At 55-60 mph with no winds, no tow, you can expect to get 7.8 to 8 mpg. Towing will reduce that by 1.2 mpg. Head or side winds will reduce that by 1 to 3 mpg. A tailwind can get you up to 9 to 9.5 - and 70 mph will drop you a lot.

Hope that answers your question.

Sounds like you know what your talking about, very specific. Thanks a bunch. Even with gas prices at all time lows, I'm thinking I'll step away from this one. My Dodge Dually Cummins pulling a 6000 lb toy hauler does better than that. Guess there's always a price to pay for even a little luxury. Again, very grateful for the timely and accurate response. Back to shopping mode....

It's not that unusual. Don't let the fuel mileage scare you off. You'll never get anywhere near the mileage with a gasser that you get with that Dodge Cummins.

I figured my gasser at 30 cents a mile, average. (8 at $2.40)

My Dodge with Cummins at 20 cents a mile (16 at $3.20).

A 2000 mile round trip to the Texas gulf coast costs about $200 more.

Our '85 Class C (26') with a carburated Ford 460 got 6 mpg at sea level and it dropped to around 4.5 at altitude. If you took the gas cap off with the engine running, you could hear the fuel gurgling as it went out of the tank!

Gas was $150 when we got the POS, When it got to $2.25, we sold it (at a substantial loss).
