what do you have how much is it and do you like it?
I was shopping around and checked Boat US..they were about 33% higher then what I am  currently paying and the coverage was not any better.  (my rate might be lower because it I have other insurance the my agent...I don't know) I'm a boat US member and have the unlimited towing thru them (even though I have a  $500 towing endorsement in my package) I thought I would have gotten a better deal.
 
 
The reason I was thinking of changing is the from a phone I made call to the company (not the agent) last year...the guy was a jerk.
