We had hail damage to our trailer this year. They were replacing quite a bit of siding. I think they said shipping was going to be over $500.
In the end, we decided to not have the camper fixed and took the money and paid the loan off, figure we will take the hit on the dents when we go to sell it. Of course, if we keep it 10 years like we planned, the dents on it won't hurt the value much - if any.
