Hi bigH again, just read your bit on body roll. I had the same problem,I took off the double springs on the rear and fitted Ausi 130 heavy duty ones,along with Koni Heavy Track Raid damper units, ( about the best we have in the UK) These gave me a 60mm body lift (with the camper body on) I also have the TD5 anti roll bar on the rear axle
(I had to use this one as the TD5 fuel tank would not allow me to fit a rear military one), I also have a heavy duty military front anti roll one fitted along with heavy duty front springs. it still rolls but feels a lot safer. the main problem we have is down to the land rovers legendary axle articulation, hence the roll, but you will get used to it, it is arrested as the spring compress.I hope this help, any questions? feel free. good luck. big H.
