I learned a similar lesson the hard way when I was still towing my boat several years ago. I had a 2013 F150 Ecoboost, factory tow rated to 12,500, towing a 9,000-ish lb 29’ boat and usually loaded down with gear. I modified it with every bolt on for towing, it had enough power to tow triple the load. But it didn’t have the chassis or wheelbase for it. When your load is bigger, longer, and heavier than your tow truck you are always going to feel the tail trying to wag the dog. I ended up “upgrading” to a 2008 F250 diesel and it was an absolute revelation. The diesel torque was great but even more so the chassis’ ability to handle the load. Simply put it didn’t feel sketchy anymore. So depending on your price range I would definitely look to a 3/4 ton diesel or gas, single rear wheel because I don’t think you need a dually for that load. Diesels are awesome but you’ll pay more to buy and maintain them, and most modern gas engines in a 3/4 ton will have more than enough power. My FIL is a contractor who routinely pulls a 30’ gooseneck 5th wheel loaded down with equipment, he had one diesel and then switched to a gas Ram 2500 and now a gas F350.
