I have watched these little coaches since they started building them,. In the beginning, they built these on the E350 chassis... the problem with them was the E350 chassis has a 4'' narrow rear end and only a ccwr of 18500 lbs.. the coach weighs 10,500lbs and with the E350 @ 12500 GVWR kinda limits the towing capacity ...now they come on the E450 chassis, with a Gcwr of 22,000 lbs, they also come now with an 8000lb hitch..so heres what that does for you...After totally loading the coach with everything we took in our alpine,.. it was off to the scales..everything full ready to hit the road..steer axel was 4480 lbs.. and the drive axel came in at 6920 lbs, for a total load weight of only 11400 lbs, the chassis is at 14,500 GVWR.... leaves 3100lbs that it will still carry..also, that leaves you 10,700 lbs total..yeah, the hitch is only 8000lbs, but easy to upgrade to 10k.. and pulling 10k you still will be under weight by 700 lbs.... pretty good huh....
