I’m reasonably mechanically inclined and as such have installed multiple Tow Bars And Baseplates on various vehicles over the last 20 or so years!
I can see that many people are uncomfortable installing their own hardware and that’s alright ,we can’t all be the same.
I have also observed that finding a place to Store a Tow Dolly and the effort involved attaching the Towed vehicle onto those things appears to me to be just as difficult as installing and connecting any Tow Bar!
Now I am reading that they are only reliable for a couple of years !
