If Ford released your van as an "unfinished vehicle" to a Conversion Van builder I believe by law they have to affix a decal in the driver's door jam with GW and tire size and pressure spec's.

 

Interesting idea Jeff. I didn't know if they did that or if they were sold as a van & the coachbuilder/customizer just 'added' to it.

 

Take a look at the Ford data decal in the driver's door jam. It will let you know if it left Ford ready to sell or as an unfinished vehicle.

 

They were typically an empty cargo van although there was an "RV" package that included chrome bumpers, higher GVW, aluminum wheels, sometimes with only a thin plastic shell "driver's seat" so it could be loaded onto a carrier. Converters added most everything else. Most of the interior stuff was meant to look fancy, but stuff like the seat upholstery was not really "auto quality"...per my post above, a LOT of people were really dissatisfied about their conversion vans falling apart and blamed Ford. Hell, my Turtle Top vans were hilarious, with panels inside covered with wood grained contact paper, cheap plywood benches (not rated to be sat in while driving), etc. But I bought a second one because they worked for my needs.

Some vans had a headliner over the front seat area.

They usually had taps to run an add-on heater and AC unit for the rear.

3 of my 5 conversions (2 campers and the Ford in the pic above) also had factory windows, which I also prefer. I think Ford put the primary tire size/pressure and GVW/axle weight sticker in, but the converter was supposed to add their own sticker showing net payload (which could vary tremendously depending on how much content was added).

If you can find a brochure for your year van and look at the equipment specs, you can see the RV option stuff listed.
