FlatlinesUP,
I think what he's trying to accomplish is enclose the lower portion of the rack (the uprights) thus making an enclosed camper shell of sorts.
Dale,
I don't know if I'd trust adhesive, even though they makes some really strong adhesive for aluminum bonding I think I would still attach the aluminum sheet with rivets or thru bolted.
Just curious have you thought of how you'd seal the created enclosure? Assuming of course I've got your idea correct I think it' be hard to seal. Do you plan on carrying anything on top of the rack?
Here's a thought I had after I bought my camper shell. I'm really into boats and a lot of the build yourself boats use a technique called stitch-n-glue. (there's lots of info on the net) I've thought of using this method to build a shell out of thin sheets of ply molded over a wood frame and "stitched" and taped together. Once you get the first layer on you laminate additional layers over top to the desired thickness and remove the molding frame. From there you would cut the window openings etc and use windows from smashed camper shells or out of an old RV or camper. The exterior is fiber-glassed over and painted so would be tough. Also, you could build cabinets etc directly into the top since all you'd have to do is "tape" them in.
I think you could build one for way less than they want for a new one, btw mine cost me $1700 when I bought it. If I had to do it over again I would try the method I describe above.
Sorry for the long winded response, these adventure mod's get me all twitterpated and I get on a roll.
