Roof racks on Fiberglass Camper shell
Here are some pics of my truck w/o the rack.
I had to pick up a 15 foot step ladder for a job, and realized that I didn't have space for it! I was sitting on the back porch one night, looking at the Dodge Caravan that I was going to get rid of (Scrapped), and had an idea. I took the roof racks off the Dodge, and they looked like a pretty good fit. This was a 91 or 92 caravan, and they only had the aluminium roof racks for one or two years. I don't know if the fiberglass ones would work.
1.You need to slide back the aluminum to access the phillips stainless steel screws that bolt through the racks into the roof.
2. mount the rack on your fiberglass camper shell. even it out and put marks through the holes onto your shell.
3. I phoned the camper shell company, and they said that it was fine to drill through. The shell was way thicker than I thought, like 1/4" thick!
4. Put bolts through from the inside of camper shell, with washers. I think these were 1/4"x20tpi. I used 2 1/2" bolts and nyloc nuts.
5. Slide the aluminum covers back on the rack. You might want to cut a rubber washer/ grommet the size of the foot. I didn't and have never had a drop of water in the shell
Anyway, you could probably get one of these racks for 20 or thirty bux at a junkyard. They're great because they have sliding rails and tie down points. I've put canoes, ladders, and lots of other stuff up there.
