I have not purchased an rv from them but on three different occasions needed parts for my Mobile Suite. All three times they had the parts in stock and they will not be undersold if you have priced elsewhere for a reason, such as distance. You will find other repair places purchase their parts from Lazy Days. The lazy days I had experience with was in Tampa Florida. From my personal experience if you need parts in a hurry then they are the place to go.
They have a computer program covering all parts from all brands from what I've seen. If they haven't got it overnight UPS.
