You're wishing to essentially drive two vehicles at once.
Why wouldnt EVERYONE just drive along towing their own personal set of supplies?
That'll be great, turret a tiger...oh wait nm he just repaired...over and over again
Not to mention how silly thats going to look, everyone towing a truck behind them.
I mean heck, why not let a C47 to a glider filled with troops, Who cares about getting shot down you have another plane!
^also a stupid idea
Actually, cant I just tow a fighter behind my bomber, that way I can be my own escort?
^another stupid idea
Get the point?
