I own a 2013 37ft. Georgetown and a friend of mine recently purchased a new 34ft Thor all Class A Gas.
I had three items to be repaired on my motorhome and all but two of them were non manufacturer items.
My friend with the Thor has virtually had to have his completely rewired and many other items to be repaired. Mind you this is a brand new motorhome. It is still in the shop. They have had this rig over a year now and had it out camping maybe at most twice.
You make your decision. We are very happy with our Georgetown.
