Arctic Fox is actually made by Northwoods in Oregon. They used to have a plant in Winchester, VA, but closed it down. But they do repair work on all mfger's units.
http://www.northwoodmfg.com/ We would consider one if we were downsizing to a Truck Camper.
Alpenlite by WRV also used to be in PacNW. They made smaller well-insulated units. My parents owned two and pulled with a Chevy S-10 pickup from WA to GA a couple of times. Don't know what's available for resale.
DRV Suites makes a few shorter units. Also not sure what is available for resale. They hold up well for Fulltime living. We're in our 2nd one.
We prefer having onboard W/D. But it does cut down on your cargo carrying capability (CCC).
