The 30/50 adapter connects connects the 30A hot to both 50A hots. This is a connection that does not trip the pedestal CB so it's not a short in that sense.
What happens with a 120V sola device is dependent on how and where it's installed. Hardwiring inside a 50A RV has potential issues when it's later plugged into a 120/240V 50A plug. The devil is in the details.
I would like someone to check it with a meter. The wiring diagram i see on net, shows the hots as bridged. I may have one out in my Rv, I will go check it with an ohmneter. You may be correct.
