When my van was off the road for about six weeks I kept my important jobs going by using my wife's car - a little Suzuki Sx4 hatch in which I put 4 x 25L barrels and an old shurflo backpack (18L) in the boot (so 118L total). I could have put down the rear seats and carried four more if I had to, but didn't.
The backpack was bungee strapped to a little folding sack truck. Would never use a backpack without a sack truck.
Put the backpack on the floor and filled from the 25L barrels.
Kept me going.
This is the kind of initial setup I was thinking of. 👍.
He's not in a position yet to go 'all in'.
It's rather slower than a van mounted tank but it can get you started and you know that if you find you have to increasingly go back for fill-ups then you are doing well and know you need a van.
Being really organised is necessary. Fill up your barrels the night before, charge your battery and have a spare - that sort of thing.
