I have a Coachman Prisim, which is based on the same Sprinter chassis, and I did the same thing my previous rig was a 38 foot class A diesel pusher. The ride, handling etc are great, I do not miss the DP. In my case the conner bed is the only issue, if he can live with that then go for it, I do not think he will regret it. No $800 fuel bills at fill up, tires can be had 1/3 the cost of the pusher, in fact you could almost do without a toad in most cases! I have taken both long and short trips with it, (longest 3,800 miles), and won't look back! Good luck
