The development of some of the newly announced rigs seems to be taking quite a long time. Truckhouse BCR, Supertramp Megatron, StoryTeller Hilt, 27North Rexrover, and several others all seem like good ideas, but haven't taken off yet. Maybe it's due to the high cost of the units and people aren't willing to put up $500k or so for a new unproven rig. At least with Earth Roamer they have been around long enough to give a buyer some confidence of longevity. I still think there is a market for something like the RexRover, Truckhouse BCR, etc., but the prices limit the number of buyers.
