used to use escort estate 1.6, though it was rubbish loading and unloading everything all the time, and fiddling changing barrels all the time. I used to take 8-10 25ltr barrels 4 in the rear footwells two in front passenger footwell and 4 behind back seats, pumped the tired to 30psi before, and that was fine, i tried to get over the barrel problem with a 250ltr flat in the back, but the car looked like it was doing a wheely when full so i didnt bother doing that, spread around with barrels is ok, though most cars are ok for 6-10 barrels. Looking at a nice big van down the road with twin tires on back axle, though currently using a two ton trailer with 500ltrs.
