I am new to this site and am also a new Navion 24G owner. We would like to tow our Smart car (2005 diesel) behind the Navion. Would really appreciate some advice and comments as to whether this is doable and advisable. Thanks Tony

here is a thread on towing an F-150 ... the advice in this thread is good ..

Primer on towing

I suggest you search this forum for "Towing a Smart Car" ... there will be at least three threads that should be helpful to you

You might consider a small trailer. They make them special for Smart cars. A friend had one custom built for about $1500. That's a lot less than installing the tow equipment. He can also use it as a utility trailer.

tony, before you do or buy anything you need to make sure you can safely tow the weight of your smart car behind your motorhome.

in general, the maximum amount of weight you can safely tow will be the lesser of the following:

the GCWR (gross combination weight rating) of the MH minus the actual weight of the MH as it is loaded for travel (includes fuel, fresh water, food, clothing, people, pets, supplies, etc.)

the weight rating of your tow bar

the weight rating of your hitch

the easiest way to determine how much weight you can safely tow is to load your MH the way you would for travel including fuel, water, food, clothing, pets, supplies and people. be sure to get individual axle weights and compare them to the gross axle weight rating (GAWR) for each axle. if either axle is overweight then either move weight to the other axle or eliminate the weight altogether. you need to check individual axle weights because it is possible to be under the gross vehicle weight rating (GVWR) of the MH even if one axle is overweight. I know 'cuz it happened to us.

next, determine the weight of your smart car. don't forget to include gas and whatever you may be thinking of carrying in the car while it's being towed.

next, learn the GCWR of your motorhome, the weight rating of the hitch on your motorhome (Class II is 3500-lbs, Class III is 5,000-lbs and Class IV is 10,000-lbs). then apply the numbers to the test above.

as an example let's say that your Navion weighs in at 10,000-lbs, neither axle is over-weight and your Smart Car weighs in at 1600-lbs. Winnebago says that the GCWR of the 2015 24G is 15,250 and has a Class III hitch (verify to be sure that's what is on your motorhome). apply the above numbers to the test:
  • GCWR minus the actual weight = 5,250 lbs
  • Weight rating of the hitch = 5,000 lbs
  • Weight rating of the tow bar = (unknown, not yet purchased)
therefore the most weight you can safely tow is 5,000-lbs (the limit on your hitch and assumes you'd have a tow bar capable of towing 5,000-lbs) which is well more than the example weight of a 2005 diesel smart car.

being safe is a simple math problem. the link you received in an earlier reply contains excellent information about tow bars, aux brakes and the like.

good luck to you and be sure to ask questions if you're unsure about anything.
