OP here:
On the initial campground attempt to hitch, the TV was enough out of alignment that the drivers side square bar was way off to the side, and we couldn't push it enough toward the L bracket to get it into place. I am not sure jacking the tongue up more would've helped. We concluded the TV had to be more aligned so we repositioned it, by pulling it forward, then re-backing up, so it was straighter. Part of the frustration was that with DW driving, she could not see the coupler on the back up camera screen,we are going to try putting some bright orange tape on the coupler to make it more visible to the backup camera. Being able to see that should help the process! Thanks again to all for your help!
