need help identifiing this roadranger

[Charlaine Nordin]

I have a 1969-1972 Road Ranger sadly the ID plate is bleached so I cannot be sure of any of the numbers on it. So the first thing is to find out what year the camper is. While the numbers are stamped the rest is bleached bur one looks to be a production date. with the sn on the bottom if someone can confirm this for me that would be wonderful.   The camper is in decent shape with only some minor work needed. I'm looking for some help as this is the only place where I found someone with the same camper trailer as me. I would love to find any manuals, schematics, and wall diagrams if possible.

Currently, My plan is to reseal the roof and vent. As well as the windows and side seams. Then replace all marker lights and tail lights. I have a couple of issues to fix but not sure how to go about it currently.  any assistance would be wonderful thank you.
