Prof, it looks like you used composite for the floor of the cargo rack, I like that idea.
Composite has become my #1 building material for RV, TV and home building additions that are exposed to the weather. It worked great for the floor or the generator/bicycle/cargo carrier.
Composite is heavy but strong. It is somewhat flexible and handles irregular contours well. It does not need painting or sealing. Main issue with composite is it will expand when hot and shrink when cold. You must maintain some spacing considering temperature.
I built the entire deck and sides on my Volvo out of composite. It will never rot! The only issue I have is that I built it when the outside temperatures were 40 degrees. At 100+ degrees it buckled some. I had to go back and remove some pieces and trim the edges on the Jointer to stop this problem.
The carrier was home-built of angle iron. 2" on the rails and 1-1/2 inch on the frame.
Photos of composite on the TV bed I built. The batteries in the middle of the bed add 1,000 amp hours of 12 VDC power. They do have a composite hinged hatch/cover (not shown). I plug them into the camper via a HD cable for both house and inverter use. The generator and solar panels (300 watt) aid in recharging them during the day. On a hot night I can run the bedroom 6,000 BTU air conditioner from the 1,500 watt inverter and the TV battery bank for two nights without full recharge. Great when you can't make noise and want to keep cool :)
