I think my next purchase is a solar oven like the SOS Sport, and possibly invest in a pressure canner to put away some meat
Les, I'm sure the SOS Sport is a nice piece of gear, but building your own solar oven isn't difficult or expensive, and could be a fair bit more portable than the pre-built models. I haven't tried using one since scouts, but back then (when dirt was new) we were able to put together stoves from cardboard, aluminum foil and scotch tape and each baked ourselves a small cake during the course of an afternoon.
I'm concerned about home methods of preserving meat. However, I did just this week buy myself a dehydrator and picked-up some london broil cuts on-sale. Just trying to decide what marinade recipe to try out first. Chicken and salmon jerky are also in the plans, and I think there's a few pounds of venison in the deep freeze that might get the treatment once I get my formula down pat.
