On the OP's list I'd go with 2 stroke outboards .. I think.

I'd add

- pickups packaged for work use instead of soccer moms and old men dragging camp trailers on pavement
- Willy's jeeps .. flatfender era .. while they lacked creature comforts, they'd go places current jeeps won't fit.
- quality external frame packs - I still use my old Kelty when the loads exceed about 35 pounds
- Winchester 94s at prices appropriate to beginning hunters
- Ruger security (etc) six series

Anyone who thinks there's two sides to everything hasn't met a M�bius strip.

Here be dragons ...
