Easy to swop between the two body styles.
A 300TDi 90 with Disco transfer-box is an excelent conversion and one that I have been driving for nearly 3-years now. Motorways, commuting, towing, hills etc, I haven't found a condition where it isn't better than the standard set-up however as I am sure someone will now say thay had it and didn't like it so I recomend having a drive in a vehicle first as that is the only was to tell if it will suit you.
