The GMC CCKW

Those pretty tow ropes and junk hung on the front bumper can be a handfull if not secured.
Loss of brakes can occur if a rope wraps around an axle.

Replica .50 can cause injury at road bumps, RR tracks and trail rides, some have barrels that will break off if the vehicle is driven too fast.
The GI Issue .50 BMG and mounts were engineered to withstand hard driving, replicas are not. The copy .50s tend to be weak in the Barrel support area, and injury and damage to the passenger and truck cab result.

If you have to add brake fluid daily from that can under the seat, park the truck, the Master Cylinder may get thirsty enroute.
