Towing a vehicle. What kind of set up

Choosing the car should take a few things into consideration as others have mentioned. validating the car you like is towable is the first priority. But a car can be towed several ways. 2 down with a dolly, 4 down with tow bars, or 4 up on a trailer. If you really like a car that isn't towable 4 down, a dolly or a trailer is still an option. Of course there are pros and cons to any method. But any method you choose must take the entire weight of the car and/or dolly/trailer into consideration. Everything you are towing is the total. The second piece to the puzzle is figuring out what you can tow. Just because your Rv has a 5k lb hitch does not necessarily mean the RV can handle 5k lbs. You need to load your RV for travel (water, people, food, etc) and weigh it. The difference between your chassis' capacity and how much it weighs is what you can safely tow. Many people are surprised to find that their MH cannot tow anything near what the hitch is rated for. So your car, the weight and the method need to be figured out before you can shop for the equipment. Different tow bars, brakes, dolly's, and trailers.
