First, I want to thank everyone for your input. I'm impressed with how quick a response I received.
So right now, I hooked shore power up and I plan to leave it for about an hour and measure voltage while it's still connected to shore power to see if I get the 13.6 VDC reading.
Just to let everyone know, when the shore power is disconnected and the battery is getting a 12.25 VDC reading, none of the 12VDC parts of the trailer are working (i.e. lights, furance, etc). I was hoping that even with a 60% charge on the battery the lights would come on. But there is nothing.
I'm relieved to know that there is no Battery Disconnect switch because I was starting to go crazy looking for a switch someone on the trailer.
I hope I can get this figured out before this weekend. Wife asked me to check the battery weeks ago and I put it off until now.....only to run into this. Gonna be cold in the dog house tonight! :(
Will keep you updated. Thank you again!
