Nancy,
So far we love our 3580, it has lots more storage than our previous unit, we love the residential feel of the bedroom, we ordered the queen size bed for the extra floorspace and extra night stand on each side of the bed. The toilet room is bigger than our last unit but the shower is a bit smaller. As Bob mentioned above the slides can be adjusted yourself, you can go to the Leppert web site for guidence or Bob can walk you through it. I will be taking mine to the dealer on Thursday because all 3 need adjusting, and a few minor problems to be addressed. You can PM me if you need more info. We really done our home work on this unit, we are completely satisfied with our decision, I just wanna get these slideouts corrected, then I will be happy.
