Newbie just got a 27' Kountry Star 5th wheel..

Once again I appreciate all the input. The tires were new right when it was parked. I think he also left the windows open a bit because it did not smell at all. And the carpet I will clean. I have a machine because my wife owns a cleaning business and I do her carpet jobs. And of course I'll be happy to post pictures. I just installed the rails in my truck today and I go get it on Friday!! I can't wait.
