Off Grid Ability
For electricity Juggernaut has a 200amp Enerdrive Battery which we charge with the 740watts of solar panels on the roof, it also charges as we drive via DC to DC charger and in case of emergency we also have a generator backup which we rarely use.
We have 300L of water, 200L of Grey Water and 220L of fuel, thick walled tyres for all terrain which create large surface areas when deflated for all types of 4wding, high clearance and a short wheel span allow us to tackle all of the 4wd tracks we have wanted to.
We save battery electricity consumption by using a webasto diesel hot water and air heating & webasto diesel cooktop. Juggernaut is completely self reliant for about a week out of civilisation comfortably before needing to come back for food, water, dump sites etc. (If you were prepared to sacrifice on some comfort you can stretch this out to 2 weeks, but we like fresh food, regular showers and using the truck toilet rather than public toilets or the bush)
