Congrats! On the towing insurance though, (and I'm sure it varies state to state) When I was in Ny, you didn't have to insure the towed object separately, it was covered by the tow vehicle. Of course, if you are towing a boat or camper that you are financing, the bank would require you to have it insured untill the object was paid off. I would imagine that your insurance on your prius would be sufficient to cover it , whether you are driving it or towing it. BUT AGAIN, check YOUR insurance co. I had a blanket commercial policy that covered pretty much everything I owned , drove or towed.
