If your only going to be taking 200 litres with a trolly or back pack then I would stick with an estate. A 4x4 may look the business but they cost a lot more to run in every department. They're designed to take a tonne for 200 litres it's way ott. I have a ranger with a 650L tank and a 2 man set up, it's cheaper to run a second motor for family stuff.
