I'm planning on buying one of the transfer tanks that TSC or all sorts of other suppliers sell. I'm looking for about 100 gallons and I'll make it so it can go on a skid of some sort and bolt or latch down in my trailer bed pretty easily so it's a "permanent" install when I'm on the road. I can take my trailer to the gas station and fill up with off-road diesel and then bring it home and unload it. I agree that the plastic barrel setup works great for diesel, but I don't want to get caught by the police transporting 110 gallons of diesel in an unapproved, unacceptably secured container. In the past, I have stored diesel in one of the 275 gallon plastic totes in the metal cages with great success.
