Perhaps this is not a concern for you but, just something else to consider-How easy and quick is the tow bar and/or braking system to lock, disconnect and then reconnect? I prefer to lock the towbar to our motorhome and to the toad while in towing mode. I am very disciplined about checking the set-up each time I get ready to pull out from a stop and did find that a pin had been pulled from my towbar after a stop at a shopping mall several years ago. Fortunately I found it missing and replaced with a spare before leaving but, from then on, I lock them. However, I wanted a set-up that I could unlock quickly and pull the toad away in a few moments. If this is a concern, check with other owners of the type of set-up you are considering and see what they do and how long it takes or easy it is to secure.
