The 42E is virtually identical to our Tour 42QD. I find it to be the most like being in a smaller version of our home. Almost every manufacturer out there is coming out with a copy of it. The floor plan was the only reason I traded my '08 Tour 40TD, which was very nice. It just couldn't compare to the floor plan of the 42QD and the one you're looking at.
I won't claim that the Winnebago is perfect. They have their known issues. But, I think they have a better reputation and would be expected to have fewer problems in the first few years.
