i just got this past weekend a g14e as a trade. i was not working becouse the f/r switch was fried and some wire cut by rodents. I got it running now but i want to add a lift and 22" tires. I will be using it around my property to haull bruch and tools pulling a little 4x8 trailer. My concern is after the lift and tires, will the stock motor and controller handle the trailer. I dont need to be fast just get around property. Would adding a 450 alltrex controller only help out or would i need to upgrade a motor also. thanks for helpinf out
