Anyone ever make something like this or use this? https://www.amazon.com/Stromberg-Ca...UTF8&qid=1500390085&sr=8-1&keywords=bike+bunk I'm struggling with a good bike rack system and thought something like this would work well. There are no rails on my roof and I dont want to drill into my roof nor my frame. Having a front facing hitch above my propane tanks paired with a folding hitch mounted bike rack seems like a great way to transport a few bikes. Having the rack fold would alow simple setup and breakdown and maintian functionality. I'm thinking of making my own version of this with some steel tubing I have lying around that clamps onto the frame like this one. Any thoughts/suggestions?
