How effective will a 1/2 ton truck be at towing a 14 ft open trailer with a 36 in walk behind, a 60 inch ztr, and all handhelds, gas cans, etc. Im thinking of buying a 1/2 ton for now as i am growing my business. Then in a couple years stepping up to a 3/4 ton. Im working out of a 1995 nissan pickup that is basically the size of an s10. It pulls my 5x8 with 52 in ztr and 21 in push mower fine but struggles with any highway pulling at all.
