ok i built me a rack that fits on top of the bed of my truck. works great and i can haul 2 full size quads on the rack and still have the bed for toolbox,coolers, lawn chairs etc. it is removeable but pretty heavy since i built it out of 5/16 x 1 1/2 steel angle. now i want to get fancy and build one out of aluminum but cant find the aluminum in 20 foot lenghts like i did the steel angle. anyone know where i can get the aluminum to do this project ?

 

Check with any local steel yard. They should be able to order it for you.
