Mine is through liberty mutual.
I'm showing on the 2012 Kodiak 300bhsl
comprehensive, no deductible at 111.00 per year
collision is a $50.00 deductible and 150.00 per year
So 261 per year.
Comp covers, fire, theft, hail damage, animal collision damage, a tree falling on it, basically anything. 100% replacement as well as contents up to a specific amount. I don't see that amount right now.
Collision means if I drag the trailer into a tree or anything else. Now the collision premium $150.00 per year can be lower if you raise the deductible. But why?
Anyhow, as others have said, you technically will have dual coverage if it is attached to your tow vehicle or sitting on your property. HOWEVER, if it becomes detached while towing and hits something or someone, then that is the loop hole, as well as if a tree falls on it while camping or it catches on fire.
Plus as you can see, the deductible is very cheap for collision and nothing for comprehensive.
