Did you purchase the RV new? If yes, then your are covered under warranty. Before you sign off on it however, you should do a thorough walk through and make sure every system (indluding electrical, water and tanks) on the RV is in working order. Don't let them rush you through the inspection process. Take your time. Let the kids, if you have any, stay at home.
If it's a used RV and you have already signed the papers, an inspection couldn't hurt. It might give you some leverage to get Campingworld to fix any issues now.
Just remember, once you sign the papers (new or used), your leverage power diminishes dramatically.
I'm attaching a pre-delivery checklist that has appeared on this this forum before. It may help you.
