How hard would it be to make some cross members. I've never looked at one up close, but am told that the end caps of the rails come off and the cross-members slide inside a slot therein. I'm thinking of maybe 1/4"x2"x6" plate for the sliders. The cross member would simply be 3/4" conduit welded to the plates. I need to carry 15 pieces of 20' long 3/4" PVC to help a friend with a water line installation. Not a lot of weight. I could buy 10 foot pieces, but, I'm also taking 3 passengers and 30 pieces would not fit inside the car. Because of the passengers I'm not taking my P.U. truck. 3 hour long trip.
Anybody fabricate something similar? Any advice? Comments? Etc.
