Hi One thing I did find with my recent purchse of a Kedron ATV was that the plated tare weight was a true reflection of the vans finnished weight including the solar, batteries, aircon, BBQ, spare wheels etc. Each van is completed and weighed. A lot of builders add this stuff after the van is plated. The only weight that eats into the ATM of 3500kg is plus gas, water and personal effects. Allowing 220 -250kg for water it leaves a fair allowance for jocks, socks & laptops. Problem with all the must haves in the newer vans that are capable of off road work that there is a bit of a balancing act to keep them under the 3500kg figure. At least Kedron and a few others have gone away from the rediculous tare weight plus 400 kg payload scenario which would see most of those vans running well outside their legal tow weight. I suppose you can't have "built tough" without some of the weight considerations and problems. Cheers Wal
