2013 Coachman Freelander 21QB motorhome (Class C). 6.0L (366 ci) V8. It's a 2013 RV model year, but it's on a 2012 truck, as most RV's are. Tires: Mastercraft LTR 10 ply - Load range E - Index 115 - LT 225/75/r16's, duels on the back.
As we travel, our total weight should decrease as we eliminate un-necessary items. Hopefully, we can reach 12 to 14 mpg.
