Hey guys, planning on starting a mowing company and until i have the money to buy a truck, I will be using my 4runner. I will prolly be pulling around 2800-4000lbs with all the equipment loaded and was curious on what mods or tweaking I should do in order to ensure that I will not break anything. I am running duratrac 285's by the way and am well aware that the ol 3.4 will be huffing and puffing around town and on the interstate. I have 4.30 gears already but would prolly need something taller like 4.88's.
