My sole 4 wheeled vehicle is a 1989 Land Rover 127 Tipper. It weighs 2.4 tonnes unladen. It's about 2 metres wide. Like all proper Land Rovers, it's sheer misery to drive, but kids love them for some weird reason.
It's surprising that there are very few proper working 4WD vehicles on general sale. The basic chassis of many of the vehicles would seem to be suitable, but they aren't offered. The big Toyota Hi Luxes are better than many, as they have more room in the back of the double cab versions.
Most of the one ton pickups in the world are made in Thailand, and the rear legroom reflects that. The big Ford Rangers are from South Africa too, and they've taken the utility market, now that Land Rover don't do the Defender.
The weight for the Land Cruiser upthread is fully laden, The kerb weight is lower. Land Cruisers are pretty capable, and are ideal if you've got a digger to deliver across a field, as they can tow 3 tonnes with ease. My Land Rover is rated to tow 3.5 tonnes, but it is a light truck. I will always choose to park it next to the most 'macho' 4WD I can find in the supermarket car park.
