2/3 of the weight on the trailer should be loaded in front of the center line of the trailer. Your three quads can not be 3000 pounds total. None of them weigh 1000 pounds alone. So your more like max 600 to 700 pounds each for a total of no more than 2100 pounds. You can load heavy to the front that's no more than 1400 pounds on the heavy side. And your tongue weight is probably about 600 pounds max would be a safe bet.. So don't load to much in the truck and your way under the max load cap, GCVW, GVWR and GAWR.. G=Gross C=combined V=Vehicle W=weight R=rating A=Axle all these are weight limits... And your front and rear axles have different ratings.. Use a weight distribution hitch and off you go..
The 500lb motorcycle in the bed might affect the payload too...
