Should I leave my Travel trailer plugged in or not?

The fridge stays on and stocked ready to go all the time.

This is the first year we didn't do that. The wife wanted to clean the frig/freezer and we just haven't turned it back on yet. Everything else is there ready to go in the cupboards. Now I have to go turn it on and fill it back up after reading that.:B

We try not to rob the RV frig when we run out of stuff in the house. The wife buys two of everything, one for the house and the other for the trailer. Costco works great for that!
