I'm going to assume most that are dogging on the OP's half ton have no idea of the capabilities of the modern half ton trucks. I've got my fair share of towing experience with many different platforms (was a truck driver in the Army and drove everything) and my F-150 will absolutely out tow even 3/4 ton trucks from 20 years ago. Obviously staying within the vehicle's ratings is a given but properly equipped (WDH ect) his truck should easily handle what he is looking to do with it. My CX2510 on a 22' equipment trailer towed like it wasn't even there, no sway, no problem braking, no drama. Its just pulls.
As for the tractor brand, I dont have a TYM dealer near me so I cant comment on that but my Kioti dealer also sells LS and for the money Kioti beat out the LS I compared it to easily. Heavier, built more substantial from what I could see and it was cheaper. Easy choice for me anyways. That was the 2t5 HP lineup though, could be different in the larger machines.
