Catching some building hours when I can.
Because I am glueing up the roof out of 1/2" sheets, I became concerned about the foam where it contacts the camper floor when the hatch is down. I put in a wooden contact piece:

Went ahead and skinned the foam with canvas. Using latex concrete block filler ($89/five gallon pail at Ace Hardware) It's very thick; you could almost trowel it on, like with a foam grout float. I opted to roll. One coat to stick the canvas, then two coats over top. I recommend a foam roller. I used a semi-smooth nap roller, ant it rolled on way too stipply for me. I sanded down the stipple and went back with a foam roller. Still stipply, but with some 100 grit sandpaper, it now feels like a textured FRP Panel. I can live with that.

Another pic to show some progress:

And one, just because. Looking like a camper now

Still working out some kinks. The hatch doesn't fit as nicely with the wooden strip, but I'm hoping the hatch closing mechanism, whatever that may be, will cinch it down. Putting the foam on the roof now. A mishap with some great stuff foam is giving me fits, but nothing that a 3 x 24 belt sander can't fix.
Rocking and rolling in the 706. Peace
