I'm not a United flyer. But, my trip this time requires booking UA to get to my destination (PSP) from my home airport (SLC). I'm going SLC-SFO-PSP and reverse, all on regionals (one CRJ-700 and three ERJ-175). I will have my trusty carryon roller with me. I have no problem giving my bag to the ramp team to put under instead of vying for overhead space. Is that possible? Also, if they want space for others, do the gate team offer "gate check" for free to the final destination? I wouldn't mind that, especially for the flight out where I've got some time in SFO between flights. There isn't anything in the bag that I must have access to enroute. And, I have no problem giving the overhead space to others who really want it.

I'm just exploring my options to be a polite UA flyer... TIA!
