I'd think insurance alone would be enough of a reason. If they "borrow" it for free, they *might* be covered under your policy (which means any insurance claims will be against your policy, even if it's their fault).
Not to be nit-picky, but if they rent it (signed contract + rental payment), then it will be covered under the renter's liability policy just like a rental car. It's a scenario that most people don't understand, but typical liability policies cover rentals. The renter's liability policy covers damage to the trailer as well as damage to any other parties (property damage and/or bodily injury) according to the renter's policy limits.
Having said that, renting out an RV sounds like a horrible idea to me.
