We just went through a similar selection process to haul a 900 lb golf car. Your options are Hydralift attached to the back of your coach, a Blue Ox hitch mounted platform, pull a trailer, or get a pickup truck and haul the ATV in the truck.
.Hydralift is expensive but seems to be a sturdy option. Requires some welding on the coach.
.The Blue Ox platform also requires a three point hitch receiver to be welded/bolted to the coach.
We elected to get a F150 and haul the golf car in the bed after considering all the pros and cons of each option.
It it were me and I did not want to have a toad, I would go with a utility trailer.
