I believe that the physics of the box truck are unfair to users who have bought the truck and the box upgrade
Why: I believe this because even with the door to the truck closed it still lets stuff fly out when flipped pretty unfair to players who have bought the truck and bed upgrade or a grand total of 180k
Solution: Make the box truck when closed act like the crates that you can store stuff in anchoring what is inside while closed making the truck worth while to grind and purchase
In short: Make the box upgrade to the semi act like a crate anchoring all what is inside preventing clipping and spilling
