We had the same problem with out "Keystone OEM furniture". It's not the best available and it's not the worst either. Problem is the temperature and humidity changes along with the UV that comes in those "huge windows on the trailer"... All that is a "death sentence" for cheap pleather.
Our solution was to order two RecPro swivel rocker recliners and since we're in the Elkhart area often, we picked them up at the distributor's warehouse for a 10% discount.
Here's the link to what we bought: https://www.recpro.com/recpro-charle...-rocker-chair/
I will say that they are significantly more comfortable than the OEM style "Thomas Payne things" that they replaced.
Had I known several years ago how "uncomfortable" the OEM chairs were and how much better these one "sit", I'd have never experienced any "pleather peeling" !!!!!
