Could this be handy when towing ?

That is interesting but I am skeptical, to say the least. I think this will need to have some sort of track record for at least a year before I would even begin to believe the numbers it displays. These guys too:

Plus I have other uses for my OBD2 port than this tow scale - I plug in a Bluetooth dongle to run my OBD2 software while driving.

 

I would invest in a tongue weight scale, those are proven and very useful for a regular trailer, not a fifth wheel.
