We sold our motorhome, if I get to race again I will be back to towing with my '99 7.4L Suburban. If I don't run much over 65, it gets 8 to 10, depending on hills & head winds.
Oklahoma has a 75 MPh speed limit on it's turnpikes (lots of toll roads in this crap hole state) mileage falls off a cliff @ 75/80. My 454" tows easier on much less fuel at 60/65.
