If the 238 had been available when we bought our Roo 23SS, we would've chosen the 238. It's one the best hybrid floorplans ever made. Unfortunately it didn't come out until 2008 or 2009 and no California Palomino dealer was carrying them. You had to order it.
The biggest "special" place to inspect thoroughly, is the bunk doors and bunk door frame area. Outside of that, it would be no different than any other type of RV.
Water intrusion happens often in this area. It requires more inspection and maintenance but that's because it has two giant holes in the front and back. The front door tends to be the one that is more susceptible since it's angled, while the rear one is vertical.
