I would shy away from the 36' one Mike, sorry couldn't resist!! I was looking at the same thing in our previous rig (haven't found one narrow enough for the 3750) and after all the considerations, arrived at the conclusion that I would prefer the slide to be as wide as the basement. My logic was that if it had room on one side or the other, that would be room for items to lodge themselves into and jam the slide assembly. This would in turn require me to have DW crawl in and dislodge the item to free the tray.
