I think all trucks running 11.00-11.99 should be lowered, 5 point roll bar, drive shaft loops, U-Joint shield, respect tire weight specifications, helmet and safety harness.

Also 4X2 4500+lbs trucks shouldn't be allowed to run faster than 12.00 it's too unsafe! Trucks running 12.00 and slower should wear a helmet and hold on tight.
