OK,
here's the short:
10K=Don't do it except for short moves, (nothing else to use, not afraid of breakage, or prosecution if in an accident!) otherwise,--And Strongly Advised!--STAY WITHIN RECOMMENDED RATINGS!--Check The Manual!.
Fill-up and load your rig--run to a scale--NOTE weight of Front Axle--Then Note Gross Weight--Then Note the REAR Axle Weight, (ADD Weight of Passengers Or other things, as required, if not on board!) this is Part 1. Loaded H2 Weight! (8600# MAX)
Part 2 is simple, Fully loaded Towed, Weighs LESS THAN 7000#--AND!--WITHIN The Gross Combined Rating. (14,000#--MAX!!)
Towed=Anything you want to, As long as you-- DON'T EXCEED 7000#, OR YOUR GROSS COMBINED TOW RATING
Tongue Weight cannot exceed 670# period!
Section 4-53 through 4-67 pretty much ecplains it all!
Except it's as POS for a TOW Rig!
