Manufacture tow ratings and dot regulations

Plenty of first rate freight out that needs so larger power unit, I make just as much hauling a 3,000 pound empty as the person hauling a 14,000 load. I can take back roads and cut miles off my trip, purchase less expensive fuel off the interstate. I can give more reasons why I would never go back to a larger power unit but just a few examples.

 

The tow recommendation a manufacturer gives for a truck is based on the equipment the manufacturer was using. When they set that recommendation they are basing it on stock equipment of the truck pulling a trailer without brakes. Either way you look at it it will always come down to the DOT officer and how they interpret their rules. All of them are different. I went through 20 states last week, 18 said I was 26k while two said I was 36k. You'll never know

 

Smart move double checking what you're hearing on the internet.

I think you said you're a mechanic so this next part is more for the people who'll be reading this thread who are not.

Regardless of the brand hitch you use, a fifth wheel hitch and king pin is something that should be cleaned, inspected, and lubed often. If you fail to do that and it breaks the Driver will likely be held accountable. The reason we tell our guys to buy the higher rated hitches is based on what we've seen over the last 10 years, The lighter duty hitches tend to wear out very quickly. I've seen expensive RV fifth wheel hitches that had been lubed often wear out within a year. They just aren't designed for commercial use.

Same goes for ball couplers, Bumper pull and Goose neck trailers. Spend a little extra cash on you're hitch for something with a heavier duty rating. Be safe.
