Purchased 2017 Denali 289RK July 2018. Sept/Oct noticed staples under EPDM backing out of roofing. Causing indentations in the EPDM. Took pictures and took unit for service, last month. Service advisor, said they are all made like that. Then they decided the EPDM needed replaced. Now warranty person states, They "want to peel back the edges and re-staple roof underlayment to frame. Service advisor, says may rip EPDM when trying to do this. First Work Order says 35 hours. Warranty claim less. No letting any one touch this until Dutchmen gets all the pictures submitted by myself and Dealer Service Department. Advise!!! Don't want issues down the road.
