Free: Contests & Raffles.
Been a bunch of good things in the way of grab & go type snacks mentioned, really can't go too wrong there. Just pick stuff you like to munch on. One thing I learned from a buddy a long time ago that I do now is keep a one burner propane stove in my rig, and I stock up on a dozen or so different kinds of canned foods, like chili, stew, soups, etc. No worries about spoiling or getting messed up since they are in cans. Several have pop top lids so a can opener isn't needed, but good to have anyway along with a few pieces of metal silverware and a couple small cooking pots.All of this fits neatly into the medium sized Rubbermaid type containers, easy to grab it and toss in the rig.Used to do the sandwich and other "cold" finger foods only, but on a cold or wet day, getting back to the rig and having a nice hot meal in just a few minutes is priceless.
