Had one of the single cab 6x6's breifly and thats now in the midst of a build in Florida.
The double/crew cab 6x6's are very rare- only 26 built. We have three of those. Just shipped a highly customized one on its way to a client in ND. The 5 door perentie is also rare with only 26 of those built as well. Just grabbed the last one of those @ the last auction. Its being built out for a fellow in Washington state for overland travel.
I have a GS model and an FFR model stateside available for purchase if anyone is contemplating one, come take a drive.
On the 6x6 we have experimented, the distance between the two rear axles limits you to a 32 inch tire. Otherwise on articulation the tires scrub ea other.
