I was wondering whether the gas mileage that I get with my 31' class A on a Ford F53 with 460 fuel injected V-8 with over drive is typical. I get between 7 - 7.5 miles per gallon at about 55 - 60 mph.

Geotex, We have a 97 36' Holiday Rambler with the 460 W/complete Banks system. The avg. MPG for 50K miles has been between 6.3 & 6.8. We tow a Ford Winstar on a dolly and travel all over the West. WE travel at or above posted speed limits, 60 to 70 MPH. It seems that you are in the ball park :) We purchased the RV in 98 with 8K miles on it. Here is the history ; Year Miles GAL/GAS COST MPG $PM 1998 6308 1045 $1213 6.0 $0.19 Added complete Banks System 1999 14725 2226 $2901 6.6 $0.20 2000 7609 1190 $1744 6.4 $0.23 2001 5759 902 $1463 6.4 $0.25 2002 7554 1202 $1672 6.3 $0.22 Jim <>< 36' 97 H R Endeavor Ford W/Banks System Hoffman Estates IL.

Have the same Ford package on a 30' 1998 Allegro and get 7.3-7.5 while towing. Goes up to 8.3 when not towing. Beats my old Chevy on an 86 Allegro that got 5.6. Pray for cheap gas prices.

Your mileage sounds pretty typical. One thing to be aware of is that at highway speeds, if you increase your speed by 5 mph you will lower mileage abour 10%, and lowering it will increase by 10%, in most cases.

Hi Geotex. Based on my experiences you are A-okay - could be worse. Now for my MPG. My '94 31' 454 Chev. would range around 8.5 - 9.0 @ 55-60 MPH & pulling an Escort Sta Wgn. My current RV, a 37' 2000 Ford V-10 will range around 7.5 - 8.5 @ 55-60 MPH & pulling a 2700 lb. toad.
A lot of variables need to be considered: ex. some gas tanks are hard to fill to the brim on a consistent basis, head winds, hilly & mountainous terrains, weight of on-board cargo, formulated or re-formulated gas(re-formulated will decrease MPG approx. 10% so I have read), tire pressure inflation & usage of gen-set just to name a few.
Perhaps someone will submit some more variables. This is & has always been an interesting subject. I check each gas fillup. If your MPG drops below your normal average, this should raise a red flag & indicate a serious problem. Hope this bit of info helps & may spur the RV veterans to share their findings.
Happy RVing to you & yours.

Reminds me of the old story about twenty years ago about the guy who came into the office bragging about the mileage he was getting with his new VW. Seems that someone was adding 5-7 gallons of gas each week without his knowing it. When he thoroughly convinced everyone about the marvels of his VW, the rogue in the office who began the prank then started siphoning 4-5 gallons a week out of his tank.
Probably an urban legend, but it sounds good. =-= Frank FitzGerald [Boston] 37' RexAir Saturn Toad No Kids/Pets on Board

Poster Bobby McNeese mentioned variables that make a difference. I would suggest that terrain ranks #1 in my experience. My previous MH ('93 Holiday Rambler w/Ford gasoline motor) seemed to roll along at about 7.5 mpg. I live in CA and mountainous driving always lowered that performance. Tours of Eastern US always seemed to produce records I could boast about, but it was on flat terrain. When towing my Saturn, I could never see a difference. I'd conclude weight is less a factor than grade. BobMcNabb 1997 Holiday Rambler Endeavor

No myth! We did that to a guy working in Cheyenne Mt. He drove the dealer NUTS after his milage fell off from 40 to 18. HIs mileage should have been about 24-25 mpg. ;p Rich & Kim, Oreo too Prowler 5ver, TrailAir pinbox Makita Genset, Solar '84 Ford F250

Variables which affect mileage: (my ranking)
1) frontal area of the vehicle 2) total vehicle weight 3) how fast you drive 4) engine efficiency (diesel/gas, tuneups, etc.) 5) headwinds 6) aerodynamic drag coefficient of vehicle 7) your driving habits (how much you use brakes, etc.) 8) engine parasitic loads (clutched fan? A/C on?) 9) elevation & terrain 10) vehicle gearing (overdrive, lockup-torque converter) 11) tire inflation pressure
Most of these are out of your control once you have purchased the unit.
So, to save money on fuel, buy a small, light-weight vehicle, drive it slowly and seldom. Buy cheap gas. Trade your MH in on a Honda Civic. This is guaranteed to say you money on fuel, but it is hard to find a Civic with a built-in bathroom and refrigerator.
