Narnia, think about what you just wrote, that you found a twelve year old and ten year old RV, same brand that water damage under a window. And you suspect it was a design flaw....
I'm not sure that you will find an RV that you would be satisfied with. Honestly, these things (all brands) take ALOT of maintenance. Water leaks abound on RV's that are towed thousands of miles over less than stellar highways. All brands are going to have a leak now and then.
