Welcome Mary. Sorry to hear about your DIL - your 'foam tent' plan sounds like a perfectly pragmatic solution to the problem.
You've got 20 years on me, but my own short term memory is a notepad I always carry in my pocket, so you're not the only one by long stretch.
BTW, someone asked if you really needed the hatch
I was thinking the same thing. If you don't need it, it seems like more trouble than it's worth. If you want to be able to have more headroom, maybe check out the Winter Warrior design or a pop-up roof section.
Since it will be parked and camped in more than towed, would a standie be more comfortable ?
Mike (the boss here) is building a foam/canvas standie that keeps the TD shape.
Well,truth be told he's not really building it right now - the project is kind of MIA for lack of updates...
Just curious, what are you going to be towing it with ?
