Best cabover design to prevent leaks

I am looking at trading in my 07 Four Winds for a newer Class C bunkhouse. I am mainly looking at the Coachmen Leprechaun and Jayco Redhawk, mainly because of the cabover design. Both claim to have the best all fiberglass design to prevent leaks, but just from looking at the online brochures and pictures I can tell they are both quite a bit different. I have read threads on this site about the leaks on the Leprechaun, but it sounded to me like it was a "recall" type issue. I can only hope all of the problems have been worked out.

Any other suggestions are greatly appreciated.
