Whether going with Paul's for recovering/restoring, or changing seats entirely, I would only consider 100% real leather on "EVERY" surface, or 100% cloth. I could never trust vinyl as an upholstery option.
After the great recession of 2008/2009, the vinyl material has been imported from China instead of "Made In USA". The China made vinyl flakes. The USA made does not. Our 2007 vinyl seating from Paul's remains in great shape. Once the old USA stock was used up, the problem started to surface around model year 2009/2010. It is not a Phoenix Cruiser problem alone. It is across the entire RV industry, from motorhomes to travel trailers, 5th wheels, whatever.
