We recently completed a DIY conversion of a ProMaster High Top 159" wheel base. We selected the ProMaster due to its interior size (including the Front Wheel Drive that provides a lower floor and slightly more interior length for a given overall vehicle length.
But more importantly, we went with this vehicle as we, too, are 6'4" and wanted headroom and a transverse bed - the ProMaster is a couple of critical inches wider than its competitors.
We used minimum flooring and ceiling (1/2" polyiso with 1/2" plywood on the floor and 1/8" luan against the ceiling joists [with insulation between joists] up top). We can hit our head, while standing, if we try - - but the reality is, we don't feel vertically constrained or challenged.
The transverse bed didn't work out quite as well due to the bed height selected. After application of the mattress (the thickness of which was a minor detail that we overlooked when doing our computations), the 'sleeping level' was just below the (added) CR Lawrence windows and, critically, smack against the horizontal ribs. This error cost us several inches. We're thinking of a 'redo' to recapture those lost inches . . . but even as is, we survive (no, can't quite stretch out completely, but then, we generally end up diagonal anyway).
Hope this is helpful.
