Hi folks, in the next month, financing willing, we will be upgrading our old motorhome to a newer one. I've never owned a rig with slideouts since my last coaches were a 1991 Allegro Bay, and our current 1989 Southwind. We are looking at class A coaches with dates around 2000-2005. When looking at these coaches, I can get an idea of problems with the engine, plumbing systems, roof, etc. But I don't know what to look for on the slide(s). Should they always move freely, make any noises, anything with them that would be a deal breaker in purchasing a used unit? Thanks, Chris g. P.s. if you know of any coaches for sale you can PM me.
