First, using your personal RV for a rental is a bad idea. RV's are finicky as it is, cheaply made and easy to break things and they don't hold up well to commercial use. Unless you are completely emotionally detached from it, I would caution against it. RV rentals is a business and should be approached that way. It will get messed up, depreciate more rapidly and cost a lot to fix things when they break and put you out of business until repaired.
We owned an RV rental business for several years. It's a business and has business expenses. At the time, MBA insurance was the only game in town. Premiums were about $800/mo for $1MM in liability. We operated under an LLC and treated like any other business. A few questions - How will you report income? How will you leverage maintenance and repair write-offs? How will you manage depreciation to offset the loss at end of life or when you sell? How will you insulate yourself from liability?
I am not sure if there is some distinction between being stationary vs Mobile. If it's on your property I am not sure how that would work. Class A's are passenger vehicles and need to be registered that way, unlike a TT which would be more conducive to your plan.
MBA provided all the necessary contracts including clauses to ensure the renter covers any damages and lost revenue for repairs. Damage deposits are usually $1,000.
Rv's are a pretty big investment for personal use, let alone using it for a business. If you want an RV for personal use and can't afford it, save your pennies. If you want a business, start a business, the 2 don't mix well.
