I'm leaning toward a KISS style build, but I'll likely do what I can to keep options open, lol. I'm going to panel and upholster the walls and ceiling, I'm having a 60" sofa bed made for the rear seating, and I'll make a platform behind it for the rest of the bed-and use the space underneath for storing camping gear and supplies. I've had a couple vans in the past with the same basic provisions, and they did the trick... but this site and ExPo has me thinkin' I should set the bar a bit higher!
I'm stirring around getting some windows for the slider and the area across from it right behind the driver door glass.
