Affect towing a trailer has on mileage
I have a 5.7 Liter V8 Gas Engine, 2WD, 4 SPD Electronic Trans, Hvy Duty Trailering Equip. and I am thinking of buying a 22ft Travel Trailer with a GVW of around 5,000 lbs. What could I expect in average mileage assuming normal driving? I know there are many factors that could influence the answer but I'm just looking for a ballpark answer. I've been told anywhere from 6 mpg to 12 mpg on the freeway at 55 mph.
