Perhaps Bill will provide the exact number, but I got the idea that there were maybe fifteen made. I have mine. Australian Martin Wright has a unique right-hand drive conversion which he has used extensively for impressive trips across his continent. I've corresponded with Martin and, indeed, need to send him a link to the build thread so he can see what we've done. (Interestingly, once it was surplus to our plans, we sent the big pressurized strut that raises the roof in the ER design to Martin so he'd have a spare.)
ExPo's Scott Brady had one for a while, using it for his Central America trip, but disposed of his not too long thereafter and I do not know where it went. It was great having a person with Scott's experience owning the same truck, as he was able to provide good recommendations from time to time. In particular, Scott changed his XV-JPs suspension to the Nth Degree/AEV setup and was thus in a position to recommend it to me when I asked how to improve the original setup.
Beyond these three, I know of three others that have passed through EarthRoamer's website to be sold, but I don't know who got them or if they actually sold. One was a new, very fancy black one with air suspension and a matching Adventure Trailer. Another was, IIRC, white with low miles, and the third was #001, which was the green vehicle which went to Central America and is the "only motorhome to run the Rubicon Trail." It is the green unit, which had something over 50K miles when offered, that is in most of the pictures shown on the ER website.
I was not/am not, of course, aware of any of EarthRoamer's actual plans, but I do know that they were aware of shortcomings with the XV-JP, especially with their tent design, and were looking for ways to improve things when their financial crisis hit. At the very least, there was talk of a correctly-designed rain fly, and also of a cool-sounding screen room attachment that would have attached to the underside (the top side when closed) of the open tent to provide an enclosed space right out your back door.
