Our 42' haulmark coach is a bit different (no garage), same motor, different trans....
We've got the Onan 10kw QD generator (and run it often while rolling down the road).
As AndyG says - your right foot can impact the mpg in a pricey manner.
I have the smart-shift 12spd (meritor) w/ the MBE 4000 (450hp, pre emissions / no EGR cooler).
I've seen as high as a little over 13 (blacksburg va to fort walton beach, via charlotte/atlanta/montgomery 131 & even had some generator run time when we slept in a rest area).
Ive seen as little is 8.9 (hot footing it in the mountains from Birmingham al to Winchester va).
CONSISTENTLY we score 9.9 (flat towing jeep wrangler) w/ generator running to keep the wife & old english sheep dog cool on our trips from houston tx - winchester va....and thats with the cruise set at 70
