chevy 2002 1500HD Silverado

Yes, yes and yes. like said earlier, load up, go to the scales and get the truck weighed with people, cargo and full fuel. Then you will know what you can tow, haul and load. I did this also, found out my GMC Sierra 4x4 HD 2500 couldn't tow what I planned and ended up buying a fifth wheel I could tow. Now in the process of upgrading fifth wheel, will be right at max for loads, towing etc. so will be upgrading truck in the near future. So long story short, get your weights, now your limits based on the manufactures GVWR,, GVCWR, on both truck and trailer and of course towing and payload capacities of the truck. Good Luck & be Safe ! ! !
