DP's seem to be built on three or four different custom chassis that have been tweaked for many years to give not only what is likely the best ride but also the most storage. Dynamax makes a model using a Ram 5500 with the Cummins diesel with 800# of torque, a nice setup. But no washer/dryer option that I could see for Isata 5. Renegade, Dynamax and Newmar make high end Super C's that give up little in amenities but are built on medium duty truck chassis. Even with air bags added and an air ride seat, am wondering how a higher end Super C rides and handles compared to a DP.
one of my challenges in this time of very low used inventory is that there are almost no used diesel Super C's out there, they haven't built this kind long enough apparently. But plenty of 40 foot DP's. So my 150k budget may restrict me to a ten year old DP anyway.
I'm not sure a 36-40 foot gas Class A will have enough power for me.
I am not going to do the maintenance on anything I own, other than carrying a good set of tools when things break, which they sure will.
