Don't believe the combined weight ratings

There is more to setting up a tow vehicle than just the weight of the trailer. Tire pressures, axle weights, hitch setup, etc. all play into it. When you bump up against a tow rating, if things aren't dialed in just so you have issues like you described. The 2500 series truck "fixed" the problem because everything about that truck is bigger and heavier. But if your trailer were 13000 pounds instead of 7500, any of those aforementioned variables being out of spec would affect how the 2500 drove, just like a 1500 series truck pulling 7500 pounds.

Unfortunately, trailer weight and length alone does not tell the whole story. Many details are lacking. Weight distribution, truck tires, weight of truck as loaded, etc. As someone stated, many variables to consider.

Although I do recognize half tons do have their limitations as do three quarter tons, and one tons, etc.

Yup. All the OP did was mask the problems with his setup by moving up to a heavier truck. I have a similar weight trailer that is PROPERLY set up and have zero problems towing at all.

My Equal-I-Zer WDH is properly sized and set up. I have NO sway.

My tongue weight is properly set up. I have no up and down motion from too little or too much tongue weight.

My truck tires are E rated and are properly inflated. I have no rolling or bouncing effect from them

My payload is within limits. I have no concerns about my weights.

One can simply spend a LOT more money and mask the problems with a heavier truck... but that doesn't mean that a properly set up half ton within its limits can't tow.

I tow 2000 miles round trip to Florida almost every winter... no problems at all.

You can believe the combined weight ratings... I would warn against believing the people who don't know what they are doing...
