Bicycles for Back of 5th Wheel

Too much bouncing on the back of a fiver. I put my bikes on the back for one trip and nearly lost them. I also carried them on the front of the truck for a few years, not bad but they restrict vision and lights a little. I now have folding bikes and carry them inside. This is the best solution for me, especially if you are parking in one spot for a while, but can be a bit of a pain when traveling as you have to move them off the bed each night.
The bottom line, each way has its pluses and minuses, you just have to go with what you feel best with.
Good luck.
