Hello, to you, too! Welcome aboard! I see you've already jumped into the forums--hope you enjoy yourself here.
If you have a freezer
on board, a vacuum sealer is a wonderful addition. Even without a freezer
, you can vac seal dinners, freeze them before you leave and put them in the icebox
. Being sealed, they will keep for quite a while, even after the ice melts. You can have some nice dinners before breaking out the canned goods.
Cabbage, potatoes, onions and carrots keep pretty well without refrigeration
. Don't let a potato go bad on you, though. Smelly! Check them every day.
