I must have one in a million truck...as well as the four coworkers that own Dodges as well.
Don't believe every blog out there. Is there a problem with some dodge trucks? Yup.
All issues have been addressed amd know fixes out there. What you have described does not sound like death wobble, and it did not affect the 2wd trucks like the 4x4's.
You are experiencing a heavy load that is top heavy, lack of proper loading of the suspension and possibly some other issues that are impossible to diagnosis over the internet.
Tire pressure, uneven worn tires, lack of experience and countless other issues could cause the issues. I'd get a real life person with experience to drive your truck and have things checked over before you blame the manufacturer for defects.
I know my setup is rock solid, but it took some decent mods to perform up to my standards and carry my load safely. YMMV, but dig deeper before zeroing in on what you have told or read are issues.
My FIL has the same year truck as you but in 4x4, with over 250k miles of pulling a very large and super heavy 5 horse trailer with living quarters. He also carries a huge genset in the rear and 100 gallons of diesel in the bed. He more than likely carries way more weight than you and he's old cowboy that abuses his equipment. Point is...nothing wrong with his truck and it sails as smooth as you can when rolling close to 27k combined (he still rodeos) all over the west coast.
