When I used a simple, inexpensive, Reese fixed arm adjustable width towbar on my Jeeps, I always left it on the Jeep. It took me just a few seconds to secure it firmly in the upright position.
Then I was advised that in CA it was illegal to do that. Therefore, when in CA I took it off and padlocked it to something.
Now, I have a
Roadmaster Stowmaster 6K capacity towbar to tow the truck. It stays folded on the front of the truck when not in use. I have never tried to leave it on the motorhome, it is too easy to just take it off the ball hitch and fold it on the front of the truck!
Yes, of course, the bottom line is, it is YOUR rig, do it YOUR way!
However, it might be a good idea to read the instructions provided by the manufacturer and see what THEY recommend! Then follow the instructions.
