I hear ya on the iced down beers but..... that only works for me for a day or 2.
What about a 2 week trip or a month? Buying ice every day is a PIA and expensive!
We have 2 plastic beer mugs full of the same stuff those blue ice packs have.
Stick them in the freezer at home and take in the RV fridge freezer.
I can pour a 38/40 deg beer out of the RV fridge into one of them and
it will still ice over on top.
We never leave home without them!
