It's not just the "old ones" - the later stuff has it's fair share of faults and gremlins as well - just read some of the "Slide won't come out or go in all the way", and "my automatic leveling jacks wont retract - and I'm stuck out here in widgitville"...
Somehow, a $10 repair/replacement on a $7K older RV is LOTS easier to take, than a $2000 fix on a newer $100K one...
