Who's insurance pays

Still no word...... other owner was under insured.......looks like we will have to claim on our own insurance. Other owner says he wants to make it right but when we told him it was going to be $350 for a person to come out and give an estimate on ours he clammed up. Told him it's 350 and that is cheaper than having to pay for campground personnel to take camper off our site. (this requires a tractor to be done) Campground charges $80-100 per hour to move campers on and off sites. When ours was originally put in it and our old one was removed it was a 4 1/2 hour job at $90 an hour.....not happy campers right now and starting to worry about leaks due to the strips of rubber that are melted that cover the metal tracks where the seams of the trailer go together.......it rained shortly after the fire. Going to try to get a tarp over it now but damage may already be done. Also the other owner has already gotten his insurance money for his camper. (did not have comprehensive coverage on it) and his company sent a letter stating they were not going to cover our damage due to this.
