aluminum roof rack
I'm looking to build an aluminum rack to go over my trucks camper shell "snug top". the bed is ~6.5' long i would like to make the rack 10' long, with it hanging over the cab. i really need to keep the shell to keep my tools dry but hate my ladders hanging out the back. the most that will be up there is 3 ladders and maybe some pvc and conduit. it dose not have to hold a ton of weight but would like to to be strong enough that in a pinch i could use it. will aluminum work what size tube pipe or angle would i need. i would like to mount my go-light and a ham antenna on the front, and some reverse light on the back. i was thinking of using 6061 t6 pipe or angle what size or what other aluminum would you think would work better and what filler wire? would mounting it to the top be good or do i need to run it down the sides to the bed rail.
i will post a pic of the truck when i can get one.
