I think that the saying "to each his own" works here. As for me, I started out using a tow dolly 30 years ago. That lasted a year! Turns out that the tow dolly was stolen from my back yard while I was away on vacation. All my RVing friends wondered if I had paid someone to steal it! That's because I continuously complained about having to use the tow dolly to haul my car around. What a pain to load and unload the car and then store the tow dolly at a campsite. I took the money the insurance company paid me for the stolen tow dolly and had my car outfitted for towing 4 down. Never looked back!
Have now outfitted 9 vehicles over the past 29 years to tow them 4 wheels down. In my opinion that's money well spent, but of course some would disagree. Anyway, that's my story and I'm stick'n to it!
