Good question Bob.....
I did that the first time around and it did work....... but as we all learn from experience.... this time around I wanted a barrier between the roof and the panels to help dissipate heat a little. I also wanted to mount them in such a way that I could easily remove them if I ever needed to replace them or move them to another coach (hopefully that won't happen for a while
).
When I had them EternaBonded directly to the roof, it was a bit of work to remove them from my old Outlaw 29H so I could reuse them on my Magnitude.
These corrugated platic panels work great but they are expensive. They are about $20 for a sheet large enough to hold a panel. What I like about them is they have little channels that air can pass through to help dissipate the heat. Then by using elevator bolts, I could Eternabond the panels to the roof, place the panels over the elevator bolt studs and then put on a lock washer and nut to secure them to the plastic panels.
It has worked out pretty well so far.
