My towing question leaving early Friday

I don't feel the need to explain but, I will. Ive been trying to buy this for months. I didn't wait. I got the call earlier in the week. I couldn't get a hot shot reasonably. It's a 70 one owner truck long bed and he said it has to be gone by Saturday. Uhaul dolly and trailer has brakes. Electric or hydro. Looks like I have a controller to hook up.
