^^^ Yep, the seller is asking what he is because he can. It is a wicked rig, no doubt, athough a little loud for my taste. I'm in a Tundra with RTT these days soon to be replaced with a Super Pacific Switchback (simple pop up truck shell) and am very happy with a truck these days after all the vans I've had. They are very nice inside (cab interior) and the benefit of a durable OEM 4x4 set up is a big draw. The only thing I miss is walk through capability, and I mean that is the only thing!
Anyone who thinks this price is outrageous should head on over to Expedition Portal and look at all of the Earthroamer clones people are building and selling. $150k is a price I would never pay but it's not at all uncommon in this vanlife, overlandlife, cash out and hit the road in style life so many are embracing.
