I use to have a class C 2018, with azdel. In the nose there was almost a undetectable crack in the caulking, on the roof the warranty had expired by seven months two R. V. repair shops looked at it the cheapest was eleven thousand, and both companies said they could not match the interior cloth and wall pieces. I went to the factory in Indiana they have a warranty section there. We live in Georgia. The head of the department looked it over and said the unit should have not left the factory with such a poor job on the caulking on the roof part over the driving compartment. Forest River has a campground where you can stay at night for free. I would drive it over to the warranty work area and at the end of the day they would bring it back. Until they decided every thing should be replaced including framing that they did some welding on it was torn back more than half of the motorhome. They would show us what they had done at the end of every day. We were in a motel by then. At the completion of the job they walked us through to see if we were satisfied. I was asked where our spare tire was it did not come with one the dealer had told us. Well we got a new spare tire and wheel they did a few extra things to the unit that we asked for to make it more enjoyable for us. Many of the things they did besides the roof would not have been covered by any warranty I expected to pay for at least some of the work. The shop manager smiled and said go and have some fun in your motorhome (which was better than new) there was NO CHARGE FOR ANY OF THE THINGS THEY DID. POINT TO MAKE AZDEL WILL DELAMINATE. Forest river is great one of the remarks that was made when I thought we would have to pay at least something was "you went to the trouble to bring it back to us at the factory so no charge for anything
