Our current MH is a 2007 Bounder 38N DP. 320 C-7 Cat engine.
When we were looking for our MH, in November 2015, we went to PPL in Houston. It was pouring down rain. The Bounder we bought was one of the few on the lot that wasn't leaking, somewhere.
We saw water leaks at windshields, a/c's, vents, etc.
The Fleetwoods seemed to have the fewest leaks. Some of the "high-end" units leaked the worst.
I'm totally satisfied with the Fleetwood products.
Before the Bounder, I had a 2000 Southwind, it never leaked either.
