I'm betting on a bad battery.
I would pull the batteries and have them load tested would be my first move before letting an rv shop touch the rig.
Any of the auto parts shops will do it free.
Many times Trailers are shipped with one battery.
Got left on the lot with battery connected. Battery got fully discharged a number of times because the 12 volt disconnect doesn't disconnect the propane carbon monoxide sensor. This hurt the battery. Add a second battery and it pulls the new one down.
It takes some time but it happens.
Get the batteries load tested.
I am thinking bad battery as well, Camping World never leaves batteries in the units on the lot. In fact, I learned after questioning why Jayco denied a warranty claim that this unit sat on the lot for 14 months before we bought it. So even tho its a 2022, it wasnt sold til march of this year.
There are a couple of things that need to be repaired, which is another story and thread I have here about the washer they installed, so having them look at the batteries is under warranty since the batteries are only 7 months old.
