Most seem to report 7-7.5 mpgs on on the newer MH's with 5 & 6 speed transmissions, while 8-8.5 mpg seems to be the norm for a 454 TBI with a 4 speed transmission for the same length MH. Maybe more HP uses more fuel? Weight of stuff inside more slide outs?
I'm surprised you need to drive so slow to get 10mpg. Back when I was running the 454 and 3 speed, I could get 10 on flat level ground traveling 65 mph. The only thing the engine had was headers. Otherwise it was bone stock.
