I was in California in a tight place and hit a low branch. It sounded bad. Like I said I took a ladder and looked all was well. But crawling up there on a ladder did not seem very safe to me. There are several aftermarket ladders that are supposed to fit ANY RV but i really wonder how safe they would be. I am going to try to get the information from the manufacturer and maybe get one that way. I agree there are just too many times I have had to get on the roof while on the road. Which I will be doing for 8 months this year.
