KW c500 double set back tandem tandem 8X8 help

[Jakyat]

This is a video of first trial run of my heavily modified king hauler converted to a kenworth C500 double set back 8X8 bed truck. These trucks in real life are capable of picking and carrying upwards of 100,000lbs+. The 1:1 of this particular truck would be roughly 360" wheelbase and would be comfortably capable of 70,000-80,000lbs. Later in the build,I will have the ginpoles complete and operational and should be able to hoist upwards of 15lbs. The test block that I am bedloading in this video and the truck both weigh about 25 lbs.
