Normally you only insure a TT for Collision and Comprehensive. Liability coverage goes to the vehicle that tows it. Stuff can still happen to trailers in storage especially outside storage, ie windstorm, weight of snow and ice etc. I agree with the above comments it is much less complicated to insure with your existing auto and HO carrier.
