2013 travel star black tank handle

[Houston Remodeler]

Doesn't the handle just screw onto the shank? Or look for a set screw

Grab the shank with channel locks / vice grips then turn the handle. Might add some Lock-tite to the thread if it keeps happening.

I noticed while driving down the road that the black tank handle was coming loose. Any ideas on how to repair it. On the gray tanks it's easy. But on the black tank not sure.
