We have a 1999 HR Endevor 36'. We have to defrost the Refrig. Norcold
every week to 2 weeks . The gaskets look good but you can slide a thick
piece of paper out when closed with no problem. So we think they may
need changing. Both upper and lower. Can anyone tell me how to obtain a set of gaskets. Camping world will install but cannot find a listing for the gaskets to be bougt.
