We snowbird from Alaska to the Lower 48. Traveled with bikes on a stout Thule rack up and down the AlCan Highway a couple of times. Just had a very a few big hitch system welded on to our 5th wheel and will leave the truck, RV, and some bikes in Lower 48. There is some discussion in the RV community about a hitch on a 5th wheel but I think that is sorted now. So we will simply fly to and from Alaska and have our rig and bikes ready to go. Theft is a different issue
