Hello again, This is a great forum, but I'm falling behind in my work! Regarding suspending collision coverage on a trailered vehicle, be very cautious about cancelling that part of your coverage. Here's why: If you are trailering your car to a show or even a paint shop or anywhere, and the vehicle becomes unmoored inside the trailer and winds up in motion relative to the trailer, you still have the potential for a collision! For example, if you have loose straps and have to panic stop, the front of your car may collide with the inside front of your trailer, and this definitely constitutes a collision, because the car was in motion. Ditto if the car falls off the trailer, or any one of a thousand different possibilities. So for the sake of a couple of bucks, it is probably better to buy collision protection even for a trailered vehicle. Cheers, Bill Hoffer, Grundy Insurance
