I've got one and love it. The storage underneath isn't the best, but all of the conversions are limited compared to a normal class A. I also got the outside fridge and TV which limits it even more.
There's on compartment on the drivers side in the rear where the power cable is. Then on the passenger side there is a very large one which in my case is 2/3 used by the cooler/freezer and 1/3 open. Then there are 2 more in front of the door, I keep the grill in the front one since the tap for the LP is in there and the other just depends on what I need to take with.
