As I look at Promasters on dealer lots, I saw one with a sliding door on both driver and passenger sides and I began to see benefits to this. I need to install belted seating for two children (probably a seat from a ford transit) and two doors would allow for flexible placement of the bench with consideration for drilling holes in the floor on the passenger side. The underside of the PM seems pretty open on the passenger side. Has anyone done a conversion with two sliding doors? Do you think it adds to layout flexibility or do you see other benefits?
