I run a Combo, 250 lay flat tank sits behind the factory built bulkhead, behind that sits an omnitrolley 50 litre, across from that sits an omni backpack on a sacktruck and in between sits 3x10 litre barrels, under the trolley sits 1x10 litre barrel and all my chargers, on top of the tank held down by a heavy duty ratchet strap sits my 100 mtr hose reel, 2 homemade hooks hang from the side panels near the back on each side, the end of the poles rest on these while the brush ends sit on the overhead parcel shelf. I work mostly from the side door.
