They are not stainless steel. They are 2mm cold rolled aluminum coated steel.
I am very seriously looking at this option for the Storm Trooper. I have looked extensively for local solutions and everyone has had problems with SS or aluminium tanks.
These Browne Davis tanks are bullet proof and I can find no problems with them.
They are very well designed, I can see they have designed solutions to most of the problems aftermarket tanks have. For example if you are fording water will not collect anywhere around the pump flange or ontop of the tank.
I am abit concerned about clearances but I hear these tanks can take a decent knock without rupturing. 2mm steel will do that!!
Cannot wait to see them installed and pull the trigger on this... then to see the petrol attendants face when I fill them up.
