IMHO, a half ton truck just isnt the rite tool for the job of towing a 30 foot trailer. 3/4 or 1 ton is what is needed. E Range tires, heavier suspension, bigger braking systems, beefier frames, all things things make for a more pleasant and safe towing tool. A 1/2 ton truck and 30 foot trailer even with all the WD hitches and other towing doo dad's will almost always result in a tail wagging the dog situation. And towing a fifth wheel is night and day to a TT. Fiver is on rails!
No sway or wind issues.
