Don't start laughing. I see people hauling motorcycles, golf carts, and ATVs on carriers attached to the back of their class a pusher. Why could you not have a fold down hot tub attachment? Granted, you could not travel with it full of water but, imagine pulling into a park, folding down and filling your hot tub and tapping into your 50 amp breaker. You would probably need adjustable jacks on the carrier but, I guarantee you would be the hit of the park. Okay, I've been married, give it to me I can take it.
