Looking hard at a TM

We are currently looking at the 2720 SL. Have had considerable experience with RVs (Class C). Would be towing with a Toyota Tacoma. We are kayakers, both whitewater and kayak touring, so the boats would go on top of the truck. I like the TM concept, but wonder about the usual things such as a dusty road (We live on one), and durability. Probably would do a fair amount of boondocking, or setting up in a campground as a base camp. Any thoughts?
