I've got the same rig. Mines an 03 model diesel 7 seater but an Auto. I've got 170,000 on mine and it's still going strong. The land Rover has some pretty fancy active suspension and braking systems. Tows like a champ and daily drives pretty well too. There are some pretty neat videos on you tube of their safety features for towing. I really like mine although I don't like recommending them to others since the last person I recommended one to had a few issues with the one they bought.
I always thought this was pretty impressive. Note the near 3 ton LR defender on the trailer.
They've improved the systems in the Disco 3 and 4
Cheers
