So far really like the custom. I would have got a second hand one but being that they're a whole new model there wern't any second hand ones about.
That tank is more an equal-sided box than a flat tank, thats the way they are I think. Grippa do a number of sized tanks, they're 400, 650 and think there's a mother, cant remember what size that is though.
Ive got some shelving on the way, its meant to be slimline and fit over the wheel-arch. Only thing is when I ordered it I hadnt taken into account the reels, so might have to move it a little up the line of the van.
