tow dolly or trailer????

I have a 2012 Coachmen Prisim, 25' class C with a V6 engine, and I tow a Ford C-Max hybrid on a dolly, with no problems. As pointed out you can not back up with the dolly attached, so you do not get into that situation. At the campsite you usually only get to park two vehicles, the RV and the toad. If you have a trailer, you get to pay for another site, or pay to store it somewhere other than where you are camping. With the dolly, most of it fits under the rear of the RV with no problems. I have towed 4 down so I know what I am talking about. Between the hitch and brake set up you are between $2,000 to $3,000 to get set up, and you must buy a vehicle that you can tow 4 down! It gets expensive. With the dolly, which you can buy new for between $900 and $1,500, you can tow almost any front wheel drive vehicle, nothing special or extra to buy. The people who say it is a PIA usually have not towed with a dolly, and are repeating what someone else said, or just assume it is a problem. To me who has done both, the setup or take down is about the same for either 4 down or dolly towing. It takes about the same time and effort, I will say with the dolly you may have to go down on one knee to pull a pin, some can not or with difficulty do that. That is the good the bad and the ugly as I see it. Good luck.
