Echo4x4 have a DB system for the D3. It plugs into the rear 12V socket in the back and then to the second battery. Therefor no cutting into the wiring!
Seen a D3 with a heavy duty tow bar in pe. Simular to the older disco tow bars.
BTW current one is really strong we been towing big loads and to date no hassle with it.
Highlift points are impossible on this vehicle.
BTW No LR tanks for them either.
