This repeated two more times at which point I upgraded to a gel cell deep cycle (their best $200+ vs the $80 original deep cycle). Went out with the "super" battery for the first time recently. Had a 2-3 hour drive to our site so I should have been fully charged, totally dead. Any ideas?

Check the voltage at the battery with the trailer attached to shore power and your converter is running.
If you charge from your TV, check the voltage at the battery with the TV attached and the engine running.
That number should be 13.5V to 14.5V or at least 13 something.
Please don't take offense but I have seen several very competent and intelligent owners who attach the battery leads backwards. Check that.
There is a fuse at the battery.Check that.
There is commonly a fuse from the converter just inside the bulkhead.Check that and the fuses in the converter.
Check the
refrigerator to be sure the 12V switch is OFF.
Come back here with the results of all that and if necessary,we will proceed to further narrow the possibilities.
