the slide may need some adjusting even if there new. i've seen a 250,000 dollar motorhome where i work at have a 2 slides that needed major adjusting. one of which pulled the carpet up and one slide that wouldn't work except with some coaxing
Our new 2005 Coachman has 2 slides and we have a dent in our flooring near the stove. Needless to say my wife is not happy. We took a 1000 mile trip this summer and used the slide 4 times. When we went to the storage yard to unload and noticed it then.
