Land Rover has gone through a massive redesign campaign over the last 5 years. The Discovery line was basically two types with minor changes between generations and major changes between D2 and LR3. It takes a while for the aftermarket to catch up.
Available right now for the D5:
- No cut hidden winch tray to fit WARN winches
- Steel rock sliders w/tree bars
- No-cut light mounts
- Underbody protection
- Roof racks
- Wheels
- lifts
It has a built-in snorkel to achieve the 900mm wading depth; at somewhere north of 1m it floats. The only thing missing is a bumper.
Land Rover engaged the aftermarket in the final design phases of the Defender - as a result, there are already front A-bars and roof racks being advertised for it, and it will have a winch tray factory option - would bet rock sliders will be quick to show up as well as light kits, underbody protection, wheels, lifts, etc.
The TrEK finals this Spring will be using fully kitted Defenders, which will preview the aftermarket accessories to be made available for it.
