I had shared this on another post...but for 2 decades we used my 60 k10 4x4 to pull a Donahue 48' quad axle trailer that was loaded with either grain drills or a 36' drill harrow from field to field. In addition to the trailer weight, the truck had a 250 gallon diesel tank and lots of tools and grease guns filling the bed. Not one field next to another...one field in the desert mountains of Idaho 30 miles to another 1700 ft higher in elevation on windy narrow roads. No trailer brakes...but we were not tooling down the interstate at 70mph either. It had the smaller 16.5 narrow tires and 4.56 posi front and rear. My point in sharing this is the truck would tow just about anything, but it was in excellent mechanical condition.
Obviously for any towing today you need great brakes, pref disc, trailer brakes, and ensure the tongue weight is spot on so the tail isnt wagging the dog. I never tow anything without AAA and a roadside kit with flares and reflector triangles in the event of an issue.
(This is what a Donahue trailer is, this is only a 24 dbl axle, ours was a 48' quad axle with 8 lug axles. Once loaded a LARGE tractor had to push it back up onto the axles, even with the low gears and in 4wd it could not push that weight):
