yup they are finally importable to the US(25 year old nonsense...), Canadians have had them for years. along with the mitsubishi delica, which i prefer. and own 2wd SWB gas american version of. i almost bought a the american version of the 4x4 gas toy but didn't like the interior or feeling driving it, it just felt sloppy granted it was a farm truck with 250k on it.
there are some super high top ones that you can stand in out there but i'm sure they bring big money. i hear people with standard roof 4x4s complaining about clearance at parking garages, drive throughs and such just with 2" lifts and bigger tires.
they are available in long and short wheel base, chassis cab and pickup.
both the toy and mitsu are great offroad and it's not uncommon to see them places jeeps with bigger tires can't get to.
nice short wheel base, meaning way harder to get high centered and a tighter turning radius.
i'm not sure how easy motor parts are to get for the diesel toys since no truck/van was ever sold stateside. but it's a toyota and a diesel it should be reliable
there's also 2wd class c versions, i bet those would cost more than a new van just to import.
i also remember seeing pop tops for the low roof hiace when i when i was looking at delica stuff too
as you can tell i like little Japanese cabovers
