and .... if you DID use the motorhome, you would also be limited to commercial van speeds, not motorhome/car speeds, AND if over 3.5t, potentially have to get an Operators license as well.
(one reason why I stopped doing shows with my Camper & Motorhomes when I went over 3.5t - too many hoops. Commerical
Insurance however is easy to get and is cheap if you did want to use the MH when selling).
