Donald,
I didn't do the installation of the Roadmaster Tow Guard I use since I bought the hitch setup used. It is super simple to use and the only down side in my book is safe storage in a campground. As to whether to use or not, we initially made one trip with and one without and will not be doing another without. In my estimation there is a complete protection of the towed with its use. I even got bug strikes on the towed with out it and none with it and this year was the year of LARGE grasshoppers where we went.
I guess the storage problem is really mine since it can be locked to the part of the hitch that I leave on the car, which if I left it on the tow bar when unhooked would solve the problem. I am just too lax and lazy I guess to undo anything other than the two pins to unhook. I use a a cable bicycle lock in the camps.
