Help needed

I use a hard wired Watch Dog. It has a Bluetooth connection that shows my 50 amp power split on the two legs 120v on each. If there is a problem with low or high voltage, it lets me know on my phone app.

Most of the Montanas I have seen have been wired with both ACs on the same leg. When I installed my Bosch washer and dryer (220 volt) I shifted one of the ACs to the other leg. Once I did that it balanced all the loads. From your descriptions I am almost positive that you have a dropped leg of the 50 amp on the pedestal. If you don't have a multi meter get one. They are invaluable while RVing.
