1965 Covered Wagon

Just bought this beauty and have grand plans to turn her into a mobile art and writing workshop space.

Her interior has been restored fairly well, but the exterior needs some TLC and we are having so much trouble finding any information about this brand/year. Any recommendations on where we could find parts, a new door, and a new decal/logo specific to this brand? Any and all help would be appreciated! Going to go watch some of the video posts now...
