^^ That vehicle is likely head and shoulders (quality) above anything built in the States, up to and including absurdly over-priced International and F-750-based trucks selling for 1M+. As noted a few posts up, a very well built small camper (Unicat or Bliss box on a Gelandewagen or 79 Series chassis) will be nearly as expensive, if not more so, than those from the likes of Tiger, ER or EC. I believe this further limits your potential customers if you are a builder. F550 with giant box for 500K or a small box with less space, fuel and water on a G-wagen for 500K? I will take the Ford, says Joe Blow. Couple that with the lack of customers in the US who really want to engage in long-distance travel outside the US, or even within the lower-48, and there is little demand for anything not built on a Superduty, Tacoma or Jeep chassis. I met a guy a few years ago selling an 18 month-old expedition vehicle, built by one of the market makers here. He had travelled, with his wife, to 3 or 4 National Parks, driven about 7,000 miles and was taking a 60k - 80k hit on the truck. For that money, you could hire a private chef, fly first class, hire Sherpas, rent kayaks, motorcycles and snow machines and have money left over. These vehicles make no sense for that type of travel.
On another note, FWC, Alaskan, GXV, ER and EC all started as small companies. With the current interest in outdoor recreation, the chances of finding this niche client, the one who wants a Maltec-sized truck, are better than ever.
