B+ motorhomes

I have been lurking in this area for some time. My wife & I still have not made up our minds regarding a 213 or 235S B+ or a 210 Popular Roadtrek. Space in the B+ is currently winning. LOL I have a couple questions, for those of you more knowledgeable about B+. Has anyone experienced leaks in the slide-out on the 235S? The 235S we're looking at is a 2005 model. Second, living in Michigan you would think that most Chevy dealers could perform maintenance on these units. After calling a couple dealers, I'm now concerned where to have vehicle maintenance done, as most say they cannot handle either the height or weight of these vehicles. Any thoughts will be greatly appreciated. If we purchase a B+, I'll look forward to becoming more active in this Forum. THANKS!
