Pardon me, but I don't know what the fascination is with the number of slideouts. I see a lot of rigs with 2 small slideouts on one wall of the living area - they provide no more (and often less) living space than one large slideout. As far as I'm concerned, the total square footage in the RV with the slides out is really the name of the game, not the number of slideouts, which just multiply the number of things to go wrong. Is it really a selling feature to have 8, 10 or 20 slideouts???
By the way, our 5th wheel has 4 slideouts - 2 opposing slideouts in the bedroom area and 2 opposing slideouts in the living area.
Just my 2 cents' worth....
