Any opinions on Dutchmen TT's

Thanks for the input everyone. I've seen a lot of photos that look good, and the owner has answered all my questions. I'm hoping to drive up to inspect/buy the camper this Saturday. I'm making a new post about this, but maybe someone here can answer as well. I'm pretty familiar with what to look for in the TT with most everything except the slide. I've never owned a TT with a slide before, what do I want to watch out for? What do I want to inspect closely?
