On my Solitude I have a 1 1/4 hith on the back of the trailer and am trying to find a rack to hold two mountain bikes. Most of the racks are 2 inch receivers and I was told not to use an adapter. I found a few that are the correct size and it says not for use on travel trailers. Has anybody else purchased a bike rack. They also sell some that go around the bumper and I was told it was not a good idea to use those either. I had a ladder type on my other RV and it did some damage to the bolts that held the ladder on the RV, had to have it repaired. I would appreciate any suggestions anybody might have. I do not want to damage my new RV. Thanks for any help you can give me.
