i agree my friend...i prefer to have all three systems seperate...doors/gears/brakes..build to last
...becouse after time door cilynders if are not perfectly aling they start loos air too..
yes there is a need for more than two airtanks...after all they are not heavy..
...also i think ill re shape the main big tank too...and i have a space in between the two to use for a smoke tank...


take care
George
