Need help with load limits

So if you register a F150 for higher rating and put tires on rated to 7500 I can tow like 1 ton?

Legally speaking, yes. If your tire rating and registration rating are high enough you can LEGALLY tow a ridiculous amount, but I promise you that it won't "tow like a 1 ton". I wouldn't recommend it either, but I am reasonably certain you are just being facetious with your statement...

That isn't exactly an apples to oranges comparison however. Structurally, the difference between current 3/4 ton and 1 ton trucks is usually nothing more than a spring pack difference in the rear, and sometimes they aren't even different (Ford F250 with "camper package"... same exact truck as a F350, but rated about 2500 lbs LESS to fit in the Class 2B designation of 10K GVWR).

On the Ram, the only difference is rear coil springs rated to 6500lbs on the 2500 and rear leaf springs rated to 7000 lbs on the 3500. The ratings on the frame, engine, brakes, rear axle, transmission, wheels, tires, cooling system, etc are all IDENTICAL between the two trucks. The 3500 is rated to have a much higher payload (sum of the front and rear axle ratings), whereas the 2500 is rated to 10K lbs (Class 2B designation). I will agree with what has already been written, the difference in suspension mounts between the 3/4 and 1 ton means that the 5th wheel hitch mounts are slightly different, but the frames are rated to the same strengths and weight ratings.

Your F-150 is not structurally the same as the F-350. While LEGALLY you can carry 13K lbs in a F-150, it isn't safe, nor smart, to do so.
