For what it's worth, my wife and I took a look at this rig last weekend. It is in fantastic shape, very clean inside and out. It has very low miles and was stored in a garage when it wasn't being used, so everything in the engine compartment seems like new - the hoses are flexible, and there are no visible seal leaks. Carl indicated he drove the vehicle a minimum of every three months and changed to fluids regularly. The undercarriage is also in good shape, see some of the photos. You can tell it has been well maintained and not used for extreme off-roading.
We decided a smaller camper based on a Sprinter Van was better suited for us at this point, but I think this Earthroamer is a gem that hasn't gotten the attention it deserves on Expedition Portal and someone is going to be very happy with it for the price.
