Commercial RV insurance: MBA vs Triad vs Any others?

Some of the rental websites have insurance policies for the folks who list their RVs for rent on the site.

I've seen that as an option, but if I do that then *I* essentially don't have any insurance covering me and the RV when it is rented out. If the renter gets into an accident that is their fault and for some reason the peer-to-peer online website insurance doesn't cover it, the other party will no doubt come after me. That's why I think it is essential for me to also have a commercial policy that allows me to rent it out and covers me.

My plan is the following...
- Have my own commercial RV insurance policy (protects me, and it also covers the renter a little bit)
- Ask renters to add the RV rental onto their auto policy (a binder) if their insurance provider allows (that would seem to cover them pretty good). Many auto insurance providers will do this for free as a courtesy for their customers.
- If they cannot add it onto their auto policy, I will likely have them book it through one of the peer-to-peer sites to at least give them some coverage in the event of an accident.

Sound like a reasonable plan?

I'm still trying to find the best commercial RV policy and MBA and Triad are the only two I have been able to find. Anyone have any experience with either?
