We have a D2 with Self levelling rear & no ACE (financial controller) and a 1999 Thor 4.0 RR (mine for work). The RR is a better ride on road and with EAS is better off road in standard form. The viscous coupling has never stopped the RR off road although I have never had it on sand. 4 wheel TC is a must on any model and this was only available post 1999 on the RR (as Ron states). Actually, the stock RR with BFG All Terrains is great in most terrain. We are surveyors and I think we give it a good work out without wanted to try & break anything.
Cheers
