Our '02 GT325 held up very well. We owned it from mid 2010 until we sold it last month, mainly due to being unable to use it very often. The original owners put 12,000 miles on it in 8 years and we did 6000 miles in 4 years. The only things we had to fix were a replacement of the original fridge and replacement of rotted-out slide toppers. The Onan generator was not running when we sold it, mainly due to neglect.
