We're planning our next trip in our Era to Alaska this coming spring/summer. We usually pull a 7x12 enclosed trailer with our trike in it behind us however we think it would be better due to the rough condition of the ALCAN hwy to leave the trailer and trike and just get a scooter and put it on a hitch carrier. Any recommendations on type of Scooter, carrier, and on the trip in general is appreciated, thanks.
