What kind of MPG can I expect?

[OtterMN]

We are switching from a Ram 6.7l turbo diesel truck towing a 43' 5th wheel to an RV & trailer. We are pretty much settled on the Coachmen Cross Country 385DS (class A diesel pusher), probably a 2011-2013... we race motocross and would pulling a 24' trailer every weekend. I would guess that the trailer loaded is about 6,000lbs. What kind of mileage can I expect to get? I was getting 8-10 with my previous rig. Thanks!
