If I'm by myself this is my normal setup. (The 40l Engel is under the tree) The blue esky is for my clothes as it's completely waterproof. I have a tarp which covers from the front rack to the back board which only gets used in foul weather. I did a 12 week trip through the Kimberley/Pilbara/Simmo in the Disco with just the swag on shade cloth on the ground & Engel in the back of the vehicle. I would not have done a lot of the places on the same diet, both liquids & solids, with just ice so, yes, I do rely on techno to a certain degree in terms of the 12v fridge plus I've always had an HF or UHF radio when out woop, so more techno there too.
I can travel very light for a fair while but, if with others, I always take their "Needs" into consideration.
I've been away with a few Swaggers & their kids & have to say that their offspring are a pleasure to be with, watching them playing with the dogs, swimming in pretty cold water, helping collect firewood, climb up an adult proof comms tower & so on, with not an Ipad in sight!
I mean swimming in really cold water is a lot more technical for an adult than a kiddy, hey?
