I think you are right in line. I also have LM. When full-timing I cut a corner too tight, clipped the side of the fiver on an overhead canopy on a store, caused 10 grand worth of damage to the trailer (pulled the end cap off!!!) and they paid every penny except my $500 deductible. And didn't raise my rates. And my rates were around $70. Now with the smaller trailer they dropped to $45. Others are right. Liability is covered when towing and when parked, your house liability covers. BUT don't take our word--talk to your agent.
