Before You Dig In
But first, if you haven’t already made a firm decision on which vehicle you plan to tow, you might like to start by reading our “ Finding the Ideal TOAD ” post. Here, we not only share our own personal journey and thought process of narrowing down our choice of TOAD (also known as a towed vehicle or dinghy).
1. Did you consider all towing options: four down, tow dolly and trailer?
Yes, I (Marc) fully investigated all of the options available to us, weighing up the pros and cons of each. We thoroughly researched all the options and still decided to go with the dolly. Why? Here is our reasoning.
3. How much time is required to hook up and secure the car onto the tow dolly? Is it a difficult process?
Yes, it does take more time and is a little more work to load the car onto the dolly than simply hooking up direct to the coach with four down. But it is not a difficult process. It takes me about 10 minutes to load onto the dolly and 4-5 minutes to unload now that I am practiced at it.
4. Do you have trouble storing the tow dolly at campsites?
No, but it really is going to depend on the size of your RV and where you plan to camp. Our coach is 36 feet long (35’10” to be exact) and so far, we have had no problem storing our dolly on our site at campgrounds. If necessary (not often) we can slide the dolly under the rear of our coach up to 80%.
6. Are you still happy with your choice to tow using the dolly?
Yes, more than three years later, we are still happy with our choice of everything in our setup. We enjoy our Tiffin motorhome, MINI and tow dolly. The combo works really well for us.
