I'm going to build a cargo area between the frame and the cabin. Somewhere between 12" and 18" of lift. Yep means we'll have some steps to get in an out of the cabin, but gaining space for AGM, 20 gallon water tank, popup canopy, climbing gear, kayak gear and the myriad of other stuff is going to be nice.

(design changed to how that area below the window will be accessed as it was pointed out the wheels will prolly block the access.)
Not shown is full width pull out at the galley for storage.
