Also... there is more to look at than tow rating. Technically I am overweight when I tow my 5th wheel in my ram 2500.
Gcwr is combined weight of the truck and trailer. I am about 23000lbs and under what the ratings are set for with some room to spare. All good there
Gvwr is what your truck can weigh when hooked up. So my truck weighs 7800ish lbs empty. Add in driver, passengers, 5th wheel hitch, and pin weight from the camper and I am like 800lbs over on the truck since it is rated at 10,000. While it is capable of more it's set for registration purposes pretty much most 3/4 ton trucks you see towing a 5th wheel and some larger TT are overweight in that regard.
Then you have axle weights (gawr) which is how much the axle of the truck is able to support, there should be a sticker on your door. I am 6500lbs on the rear and I think 6k up front, and I have room to spare on each of these weights.
Then you have tires. I dont think most passenger tires have a very high weight rating but dont know of what most are off the top of my head. My truck is 3650 per tire so they can support 7300lbs combined for each pair and I am well within that weight as well.
With that said it's got to look pretty bad or you have to do something dumb to get pulled over and weighed. However you could be held liable if you were in an accident.
Just throwing that out there for consideration.
