I toured a Dynamax on the Columbia chassis at the RVIA show a few weeks ago and was not impressed. They seem to try to hard to make it look aerodynamic, and that takes away a lot of the interior space. I almost felt claustrophobic in their compared to my Show Hauler. The interior is very nice, but just like a pusher interior, thin walls, doors and trim. One thing I do like is the electrical system they use. They are all going to a smart system which monitors input current, will automatically shut down items that cannot be supported due to sags in power.
For the money you can get one decked out Show Hauler, Renegade or NRC and still have change left over for a stacker trailer and fuel to get you where you need to go for the year.
