2017 Denali 289RK. Purchased 7/7/2017. Warranty on roof 1 year. Used 3 times. July 2018. Took unit back to dealer. Staples under EPDM backing out of roof under EPDM. None have broken thru EPDM roof membrane. Dutchmen approved slight fix in July 2018, however dealer did not have the time to repair prior to our next planned trip. Used Labor Day and Thanksgiving of 2018. Took unit to dealer on 2/7/2019. Dealer still has unit. Dutchmen balking on repair at this time. Each time I use unit, I discover staples (more) backing out. So what good would have the July 2017 repair accomplished. I have reached out to Customer Service at Dutchmen and Customer Service at Camping World (dealer) Still in deliberations.
