You can ask for it, but most likely they'll not give it to you. What you really need to do is thoroughly inspect it yourself (don't believe a salesperson that says they do this themselves - it's YOUR money, not theirs!) with slides in and out, does EVERYTHING operate, fresh water enough to check for leaks (and they won't like doing that either!), all appliances & electronics, and a lot of other things. If you're not familiar with RV trailers, RV Consumer Group is a good starting point - they cost a bit of money, but think of how much you're spending. I've had various types of RVs for over twenty years and still bought their package when we started looking for something that would cost us over $25k. I modified their checklist some, but the info they gave me had several things I'd never thought about.
