Bike rack options

I too have spend a lot of time on this, and here is my solution. I have 4 teens so 6 bikes to figure out. I had a 4 bike rack which I tried on the rear of the trailer, it is an older (2004) that has a hitch welded to the frame. I only put 2 bikes now due to the weight and bouncing issue experienced by others. I use a ratchet strap to hold these in place which reduces the bouncing. For the other 4 I have built a custom rack modelled after the arvika rack which has these sit above the propane tanks on the trailer tongue. It is a 2x4 wooden rack that has 4 thule bike racks attached. I am really pleased with how this turned out, the bed can be retracted with the rack attached with just enough clearance. There are some pics of it in the mods section. Good luck
