Do you know the answer to the Monaco Question...?

Leave the propane on for the fridge during travel. It's the same as your 99 Dolphin.

If it's a Norcold fridge, call them with the model #, and serial #. They will tell you if the mod has been done, or if it's even needed. If not, have Premier/ Premium, where the coach is, do the mod for you. Takes them all of 10 minutes to do it.

If you want to run it off the inverter, turn the inverter on, and switch the fridge over. Easy peasy.
