You made a good point. I think the fact that in North America we only have a handful "high end" expo truck builders makes it easy for those builders to charge what they can. In Europe, you have almost hundreds to choose from. Therefore you can select by quality and price. For example: $600.000 will get you a true custom made, very well built Unicat or Krug Vehicle. I have been employed at Unicat and can tell you first hand that absolutely nobody in North America is even coming close to their quality.
Yes largely my point. $700K in Europe you could get a true ExVe, on a proper 4x4/6x6 truck chassis with all locking axles, proper quality and design. $700K Earthroamer you do get a nice interior, but also just a pickup truck with non locking diffs that could get stuck in a wet grass field.
