CEL Engine Codes when towing

I tow a small 2200 lb teardrop camper with my 2019 JL 3.6L V6 Automatic and on two trips have gotten the following codes:

P0171 System Too Lean Bank 1

P0300 Random / Multiple Cylinder Misfire Detected

P0137 02 Sensor Circuit Low Voltage Bank 1 Sensor 2

P2096 Post Catalyst Fuel Trim System Too Lean Bank 1

This only happens when towing and will correct itself after normal driving. It is most likely to occur towing at moderate altitude (> 4000 feet) and after towing for a while. The dealer looked at this once, but could not find anything because the codes had cleared by the time I got it in. I have another apt in a few days and will try to have them read the codes today while they are still active.

I have no idea if this makes any difference, but this has only happened (twice) when I have a bicycle mounted on a front hitch mount, which could disturb cooling and air flow, but not enough to notice on the display.

Any ideas?
