My '08 110 is certainly a rougher ride than my '89 110 County was, but I just put that down to springs that had done about 400,000ks less than the county had.
I fitted a ARB winch bar and winch farily soon after buying it, and fitted "range rover red" springs to take the extra weight, the car seems to ride fairly smoothly now.
I also run my rear tyres at about 40psi, (instead of the stickered 48psi), which helps when its empty. I have found it drives much better laden, also it feels more at home on gravel roads than on tarmac.
You could always fit Disco 2 rubberised shock towers in the front, and rubber isolators under the springs in the back.
Cheers,
Tim
