I use a nissan 4x4 with a freedom trolley.It does about 30 mpg,can fit in folding ladders, 10 x 25 litre barrels,could get more in if I stacked them.
I am looking for a roof rack to carry my normal ladders,also looking for a flat water tank so I can stack the barrels on top as I have started running out of water.
Ithink the nissans have a bit more room in the back than the mitsu s
