Dude... Please... Truck is not early game scout unit. Its not even a combat unit.
This is pure fail in design from Relic cause they did not forsee that people will use it to push out of the cover.
Thats why you have Kubel to help your SP, not truck.
This is building unit, not scout or combat. It negates hidden at guns, gives you 100% chances to win first engagement and few other issuses that truck is not designed to.
100% chance? pleassee man thats a L2P issues there you know u can put infantry in garrsisoned buildings right?
Ive beaten man OKW truck pushers, and many times destroyed their truck as well which is essentially gg if you rush him quick enough.
However in the hands of a skilled player yes the truck can be op and on maps/capture points with no buildings it can be devestating for early game.
Not one of the biggest OKW balanced issues, but definitely not game breaking.
