Hi Vintage,
I myself do not know the brand but may be able to help a little.
The features of the camper and that you are out west point to that odds are very high it is not a Sunline camper. We know them pretty well and the flavor of the design rings through all of them.
This may be a long shot but never know it might create a good lead. Sunline would place a tag with the camper VIN number under the floor plate of the main entry door. I do not know if this was a Sunline thing or industry standard and companies may have gone in and out of doing it.
See here on mine. I had to pull the door out to re-square it and my tag showed up. You really do not have to take the door out or in my case the door frame, just the cover plate that is inside the camper that spans from the door sill plate to the inside floor.
Here the entire door frame is out. You can see the black tag. Sometimes they were metal. Mine was the older plastic punch and stick label.
You can see here the door frame is on and the tag is still exposed as the tread plate cover that spans from the door sill to the floor is not on yet.
If by chance yours has a vin tag there it is the start of a hunt to the manufacture.
Sunline also on the older camper stamp in the steel of the ball coupler area a VIN number. Again this may be a Sunline thing but others here on SOC have found their VIN on the camper tongue. Somewhere on the forum there is a pic of this stamped number location. Sunline Fan may have posted it or another member. Sunline stopped that practice a long time ago and the newer camper have a VIN plate on the front left side of the camper.
They may be a long shot, but might help. And then there is, did old time campers even have VIN numbers?
Old boats did not have hull tags or VIN plates like they do now. I had to register a 1965 sail boat for the Boy Scouts and had to take the 4 digit hull number to the ODNR to prove it was a boat and they issued a new VIN tag before we could register it.
A lot of this VIN system was created to help stop theft. When that serial number popped up trying to get plates for it, it better not come up stolen. In Ohio when my camper which was born in PA came over I had to prove the VIN on the camper was on the camper. Had to haul it to the BMV for inspection, that was fun.... 32 foot camper in a mall parking lot. Seems OH does not trust a PA title.
Good luck.
If and when you get into fixing the camper, many are built in the same methods and we can help a lot more in that area.
John
