There's nothing wrong about towing 4 down. A tow bar with telescoping arms makes hookup much easier (the arms lock at full length when you start pulling. Yes, you need to get compatible baseplate to mount to the front of your Toyota. Do get brand name equipment for peace of mind. I have used the fixed tow bars. I would hook a very light chain from the ball end to the radiator support so it held the ball mount just high enough to clear the ball on the tow vehicle. This made lining up for hitching relatively easy although still a pain compared to one with telescoping arms.
