Yes, two different companies.
The thread title made me initially think it was perhaps an Earth Roamer but the CL link shows differently. The first "Earth Roamer" that now carries that brand name as alluded in Kaytag's posts was initially built on a Dodge P/U truck with a modified camper shell- I think there was only one, perhaps 2 of those types built (I would have to check back in my old TDR quarterly's)... those trucks/TC's evolved into the ER brand when Ford offered 550 chassis and Dodge at the time did not.
ER is totally different from the OP's link.
