Mine is a Hardtop so there is a bit less weight in the back but I have a rear drawer/storage setup and second battery that adds about 150kg empty. So unloaded 150kg more than an empty Hardtop. That's 90% of my driving.
The rest is touring trips and the back is full, a second spare on the carrier, lots of wine :D, 60ltrs of water, tools, spares, food, camping gear etc. Probably add 400kg to the previous 150kg.
I run reasonably soft springs though, 180lb fronts and 270lb rears with air bag helpers that only get used when loaded.
With the Raids on the factory setting it was a bit of a marshmallow but with the rebound wound to max it is close to perfect.
If the rebound is too soft you'll notice it on the corrugations, they'll literally shake yourself and the Deefer to bits.:mad:
