According to the Trails West Campster
Brochures the propane refrigerator
was an upgrade option. The standard configuration was to have an icebox.
They had other optional upgrades as well, such as a furnace
which this one looks to have.
So yes your Campster might indeed be different versus one where the buyer purchased upgrade options.
Mine seems to be standard, no upgrades but I do have ribs and a flange on my popup roof. Not sure when they changed over to that style, probably late in the manufacturing cycle as no one else in this group has that. I can't tell for sure but I think this one has that flange on the pop top roof.
It also has the same hitch configuration as my Campster with an additional riser section added at the ball end of the tongue to make it taller. I was suspecting mine came that way from the factory but most people did not seem to have that riser section so I was not sure. Now I know as this one is identical looking
