Upgrading - Questions about cracks and thermal checkering
Well we're going to upgrade motor homes, I think! In our travels I came across a 2004 Gulf Stream, this is when I was first introduced to hairline cracks in the body panels. So I research this site and to my surprise found cracks and thermal checkering was a common problem. So now I'm looking at a few DP models, Monaco Knight 2001, 300 Cummins and a 2000 Monaco Diplomat 275 Cummings w/ programer chip. I seen the Diplomat a few weeks ago and the light green/dark green full paint didn't appear to be cracked, but I wasn't aware of the problem at that time, only found out a few weeks later when I seen the Gulf Stream. I find that the Diplomat at 38' was lacking a lot of storage compartments for it's size. The Knight is white with a red bottom & strips, but I'll only see it in a few days. The 3rd option would be a 2003 Mountain Air, gaser, 8.1 on a workhorse chassis, 2 tone grey paint job, but I didn't see this yet either.
So my questions are,
1) What RV manufactures and what years were affected with the Owens Corning fiberglass panels?
2) Is there a way to determine if the Owens Corning fiberglass panels have been used on a particular RV?
3) if the exterior bodies don't have any cracks and appear to be free of manufacturing defects, is it safe to assume that there will never be any considering it's age?
4) Would the Monaco Knight or Diplomat, which one would be a better RV?
