We have a 2003 Granite Ridge 3100ss motorhome that still looks close to new inside and out, so I feel it has stood the test of time a bit. Inside has solid cabinets, drawers and counter top. Nothing looks worn. So far nothing has gone wrong or needed to be replaced. I keep fingers crossed. Only problem we have had is low CCC rating, so we need to be careful how much stuff we carry. I do tow a 16 foot boat with it and have had no problems with power or keeping up with traffic. Most of our use is dry camping 100 miles from home, we camp year round 12 to 15 times a year, so gets a lot of use in the living area but not a ton of miles. We have had 4 motorhomes over the years and the Jayco is the nicest. We do keep it under a carport and this I'm sure has alot to do with the condition of the exterior.
