Using this logic, all of those fancy 30+ foot travel trailers out on the American roads can only be pulled by fully loaded dump trucks.
There are a lot of folks towing #10000 and #12000 campers with 3/4 ton pickups. Even with #1500 on the tongue the trailer is heavier than the truck.
No... that's why they have trailer brakes. Done all the time, and it's no dif than a tractor hauling a loaded trailer. Also, that's why a lot of the big travel trailers have a 5th wheel system rather than a conventional hitch system now... easier to handle, and better handling and load distribution.
(BTW - 3/4 ton is the load capacity, not the weight of the truck. My 3/4 ton P/U weighs about 3 tons empty...)
Nope, nope, nope.
Alright, class is in session. Pay attention and everyone lives.
Tractor-trailers and fifth-wheel trailers behind pickups carry about half the weight of the trailer on the truck. That's how 20,000 lb. semi tractors can tow 60,000 pound trailers. When they are hitched up, the truck weighs about 48,000 lbs. Same thing but on a smaller scale with pickups and fifth-wheel trailers. It's NOT the same thing as towing a bumper-hitch trailer that has relatively little tongue weight, and puts that tongue weight behind the truck's rear axle where it lightens the front end and makes matters even worse.
When you tug a trailer that weights twice what your truck does, the trailer has more traction and inertia than the truck. Try stopping on an uphill gravel road with that setup, see if you can get going again. The trailer will always "win" if it is heavier and you get in a screwy situation, whether it's a sudden swerve or whatever.
Oh, and 1/2 ton, 3/4 ton, and 1-ton isn't really the load capacity, it's an old term that stuck around from the '30s and has little to do with actual ratings nowadays. It's just a popular name for identifying light-, medium-, and heavy-duty pickups.
