It's rather bewilders me why there isn't more interest in these types of vehicles, especially since when you get to your final destination it inevitably has some off-road aspects, where getting stuck is a real possibility!
Considering the all up weight of these vehicles is over three tons, and also considering in some of the more remote sites in; Let's say the Lake District, in heavy rain, tends to be more than a little evidence of previous people with camper vans, trenching out the site, to the extent that some of them look like ploughed fields, in one of our recent escapades, up there in the rainy season, it was only to evident.
Also there's just a few true van type vehicles, with four-wheel-drive capability, the Volkswagen type 5 being just one of the examples , and you could be almost be certain, that the myriad of other SUV type vehicles out there, that frequent today's roads, will have nowhere near the opportunity to actually 'go off tarmac', then what a Californian would do every single day of its intended usage, which is camping off road at the end of the day.
So for me considering the fuel economy is almost the same as its two wheel drive counterpart, it's the 4-motion every time.
I don't know any other true campervan that's made today with four-wheel-drive capability. precisely the same mechanical system that's in the Landrover Freelander 2,
But with a far superior ride quality then the Landrover product... Unless anyone else knows better?
