They're made in Jefferson City, Missouri. To my knowledge of the "work N Play" and the Pla mor" brands is they are a hybrid between cargo trailer and camper. They still have fiberflass sides like the new campers have, however a cargo trailer floor and roof.
Continental cargo is a trailer company that will install bath and kitchen packages. that is what I ended up with. I found a used 2009 model. They are not as luxurious as some of the other toy haulers, but I am out 4 wheeling not on a luxury vacation.
Now if your use involves going to a place with your motorcycle loaded, then taking a day trip and coming back to the camper at night, you might be looking more for luxurious or amenities style toy hauler and Pla Mor is right up your alley.
They are a solid built trailer and I probably would have bought a used one, however the Continental showed up first.
