Gosh,I use a receiver mount conventional rack and put our tandem on that myself and keep both wheels on. I just took our CoMotion to Maine and back to Pittsburgh again this way and we never have any problems. I just cannot see why anyone would want their expensive bike way up there in all of that wind with bugs, branches and grit continually asssaulting it. Take a look at the pix I posted of it behind our minivan in the perfect vehicle for tandem thread. Behind the vehicle the bike is pretty protected from a lot of stuff and you likely get better mileage that way too.
