Bad assumption, Mark! Everyone's trailer is not like your trailer.
The OP's trailer is a 2023 Salem Cruise Kite 240BHXL. The refrigerator is an EverChill BGC-46. That refrigerator happens to be (as the OP surmised) 120Vac only. It DOES NOT work off propane. The OP could run it from an inverter--not sure whether his trailer comes with one or not.
That refrigerator draws 0.8 amps at 120 Vac. If it were run from an inverter, it would draw 8 amps (or a little more) from the 12Vdc battery.
A typical trailer flooded Lead-acid battery has 60 amp-hours usable. So let's say that the refrigerator runs only 1/3 of the time. That means that in a day, the refrigerator would consume 8 amps x 1/3 x 24 hours = 64 amp-hours. That means that the refrigerator will drain a full battery down to the safe point (50 % charge) in a day. If the OP is planning to dry-camp, he can:
- Not use the outside refrigerator
- Add another lead-acid battery to extend the trips to two days
- Invest in Lithium batteries which have about double the usable charge.
- Invest in enough solar to recharge the battery(s) and hope for sunny days.
- Bring a generator to recharge the battery each day
