This post comes up frequently. I would have suspected being a member since 2006 you may have seen a few. I have done both. Dolly is a good method when you have a vehicle that can't be towed 4 down - that's really it's only redeeming value. That and it can be used on different vehicles - maybe. Dolly's are a hassle to hook up, big and heavy and another item to maintain. I could not wait to get a vehicle to tow 4 down and get rid of my dolly. 4 down is soooooo much easier. I can hook up our CRV and get it ready to tow in about 1 minute - literally. According to CRV manual I have to let it idle for 3 minutes, usually I hook up while it's doing that and have to wait for a minute or so for the idle time to lapse because it takes me so little time and effort to hook up. People will tell you they love their dolly and it's not much hassle and I say they are making themselves feel better. If all vehicles were able to be towed 4 down, the dolly market would decline to close to nothing pretty fast. People who have a dolly only do so because their vehicle can't be towed 4 down. Unless you enjoy lugging the dolly to the hitch, hooking it up, hooking up the wires, trying to line up the ramps, drive up on them (good luck with that if the ramps are wet), put on the straps around the wheel (pretty dirty job), tightening the straps, and then driving for a while and stopping to tighten the straps again - and undoing it all when you get there. Add to that unhooking the dolly and lugging it to store it somewhere. With 4 down, drive up close to the bars, put in 2 pins, attach the cables, plug in the lights and done.
