This is a serious message. Every tow vehicle has a maximum tow capacity, and you are just asking for trouble if you exceed it. At best, your tow vehicle will wear out faster – drive train, brakes, suspension, and frame. Not so good, you can get ticketed for driving an illegal combination, and if you’re in an accident and the weight problem is discovered you’ll have a very hard time convincing anyone you aren’t at fault. At worst, you’ll catastrophically break something, or be unable to stop your trailer when doing so is absolutely vital to preserving someone’s life – possibly yours.
But go to any truck sales lot and no matter how big your trailer is, I’ll lay money that the biggest truck on their lot is big enough to tow it… according to at least one of the salesmen who want to collect a commission for selling you that truck.
Don’t believe them.
Somewhere on your trailer there should be a placard telling you its GVWR, or Gross Vehicle Weight Rating. There’s also a placard on the truck, usually on the driver’s door frame, telling you its GVWR and also its GCWR (the C is for Combination). Add the two GVWRs together; if the result is bigger than the GCWR, the truck is not big enough. Period. Close doesn’t count.
Then it gets a bit more complicated, as there’s also an issue with the trailer’s tongue weight – how much weight load it puts on the tow vehicle’s frame and tires. But if the truck passes that first test, the odds are good on this one.
These folks got some really bad advice…
