Here's something I thought was really cool. I'd been bouncing ideas in my head how trim the insulation inside the camper. I didn't want to add another skin inside to cover the spars, but I didn't want an unfinished look either. As I was about to fall asleep a few nights ago, and idea popped into my brain.
I picked up some 1.5" PVC pipe and ripped it lengthwise. The first thing I did was to mark a centerline.
After the line was marked, I clamped it to some sawhorses and cut it. I had no problems cutting the PVC with a fine wood blade in my jigsaw. It cut through the entire piece in one pass.
I then took a piece of 1/2" pink foam and wrapped it in some spare material I had laying around. I then countersunk two screw holes in the pvc and slipped everything in place.
Obviously when it comes time to do the real thing the foam/fabric will cover the entire width. This was just an example to see if I wanted to do this.
This is the finished look. Cool eh! It really cleans up the look of the interior. It's much cheaper than trim, and it has a few added benefits. The foam will act as insulation. I don't need much here in Texas, but it's not a bad thing to have. The panels aren't glued in place, but held in place by the PVC. If you ever need to access the areas behind the panels all you'd need to do is unscrew one of the PVC sections and pull the panel. This would be helpful for adding wiring, vents, etc. later if you decide to modify your build.
Just a few notes. I'll use 2" PVC next time instead of 1.5". By using 2" PVC I can control how tightly the foam is pressed into place by how tightly I screw the PVC onto the spars. The 1.5" is too short to pull the foam to the ceiling tightly. The PVC will act as a full length clamp. Another thing I'll do is paint mine. I'm going to paint the PVC red to give some nice contrast in my camper. One cool thing is you could always leave it unpainted. I took some 220 grit sandpaper and sanded the lettering off the PVC.
The foam insulation will run about $30 for my camper, $15 or so for the 3 pieces of PVC I'll need, plus the cost of fabric to cover the panels. Not too bad, and I think it looks great.
