Going to make my own mounts using aluminum angle iron. Going to cut into 3" or 4" lengths, drill hole and attach with bolts to form a Z. Then mount to thin roof with well nuts, 2 per mount and soaked and covered in 3M 5200 adhesive caulk.
Question? What gauge aluminum do I need 16 gauge or 11 gauge? Using 6 mounts instead of 4.
Looks like some on Amazon are very thin and other are thicker.
Found it at HD heavier 1/8" equals 11 gauge, going with that.
I did something about the same. The top angle was 2" wide the bottom 5"
With 4 staggered holes. I mounted them close to the edge. On the last two RVs,I found that along the edge of the roofline , there is something substantial to screw to. My current RV has the same roof as yours. I used Polyurethane. (the same stuff that glues in windshield's
) You can find it at HD (look in roof sealants).
Good luck wit your project!
I only want the panels 1" to 1 1/2" off the roof so not too much air can get under it while driving and lift it off. I have driven 80 mph in places like AZ and UT where the speed limit is that high. Also down to 60 mph with 40 mph gusts so I want as little wind effect on the panel.
I wouldn't mind having a broader base and maybe use 1 1/2" for the portion mounted to the panel and 2" mounted to the roof leaving it extended up the side of the panel frame.
