We have a cargo carrier like what downtheroad linked to. DH welded it to the frame of our 26' fifth wheel, then put a side bar on each side to hold it steady. Good thing he has a welder!! We tested it.....put two 50 gal barrels on it, and some other small things (sat. dish tripod) and he drove around on bumpy roads and the highway and I followed. That is one reason he put the side bars on it to stabilize. :) :) So far we haven't had a problem! However, I do believe the bike rack is a better option for you for what you're carrying. It would be hard to get a table "tied" to the cargo carrier, I'm thinking.
