I haven't done this yet but I have a 250cc dualsport motorcycle that I plan to transport on the back of my toad (a 2005 Caravan). Originally I'd planned to carry the motorcycle on the back of the RV but realized it made more sense to carry it on the back of the toad. That way I'll be covered when I'm traveling from one place to another in the RV, as well as when I want to do some trail riding at places I've explored with my toad. Of course I don't know what type of motorcycle you have and if it'll fit on the back of your tracker.

PS I have the Caravan because it gives me a comfortable place to sleep when my explorations have carried me far afield from my RV. I look upon it as my mini-RV.
