How would one of these work. It siphons or pumps depending on which way you turn the crank.
Had one in my automotive shop and ran it with a half inch drill.
That can help partially, but not completely, solve the problem for many.
Take this customer for example. He was using a pair of caddies like that, 30 gallon claimed capacity each. He had problems with the rough terrain, heavy weight making them hard to load/unload, and inability to fill them to their claimed capacity saying he could only get about 20 gallons in each of them reliably without spillage happening during transport.
He bought two of our products. Uses them to gas up his rental boats. Seems pretty happy with them.
