Every RV, I've owned over the last 40+ years got less than 10 mpg. No matter WHAT it was....Moho, 5er, TC, or TT. The "best" fuel mileage rig is my present 31 year old 460/ZF-5 F350 running just over 10,000lbs loaded and ready to camp. Our S&S runs around 4,500lbs ready to camp and Red has gotten a 12 year lifetime average, with the TC on her of 9.4 mpg and she gets 14 on the highway empty.
I believe the 7.3 gasser will be close to that, but with the 10 speed trans should drive light years better than my old truck.
The new ten speeds are a game changer for gassers. Ten speeds put the engine in the right place all the time, no lugging, no screaming. Really sweet. I haven’t been this excited about a vehicle in a long time. We are loving our new F350 gasser. With the added cost and complexity of diesels, they are getting much harder to justify. We hauled about 12,000 lbs on one trip this summer-no problem at all. I have not missed our previous diesel for one minute.
