Just back from a great camping vacation in New Hampshire to attend our granddaughter's wedding in the White Mountains. We stayed at two campgrounds that were great. The trip was greatly degraded by the rough condition of many of the northern highways (not NH or VT), for which some states have the nerve to charge a toll. Just read that some northern states divert up to a third of their fuel taxes to other things than highway upkeep. The roads were bad enough to loosen my 2" ball's nut! Yes, I caught this before it became a major problem. Never had this issue before while towing. Sad! Sad!
Back to the subject, the bottom door seal on my 2013 Parkliner
has deteriorated due to weather and age. It is in bad shape. I have tried the self adhesive seals which do not hold up. Does anyone have a source for an OEM seal replacement ?
