All sorts of stuff in a good military surplus store can be used in camping and back country travel. In the past I've used good down-filled mummy sleeping bags, tents, tarps, a wide variety of ammo cans and other containers (for both cargo and liquids) and canteens, alpaca-lined deck jackets and other winter wear, folding shovels, hell, just all kinds of stuff.
All depends on what your local surplus store has. As already mentioned in this thread, sometimes the inventory is import knock-offs, though for the right price, even some of that is a decent value. I got some small molle bags I use on my bike that were knock-offs. Other times the store leans more towards patches and knives and small stuff.
One of the best surplus stores I've ever been in was in Toronto, but that was in the 70s; I'd be surprised if it was still there now. There's a great store in Lexington KY that I've thought about ordering from online:
Army Surplus Warehouse, that has a
huge inventory and is located in an old 5 story warehouse. I don't think all of it is showroom, though. I plan on stopping in there in person sometime.
I also like
keepshooting.com for online shopping of military surplus items. They send me email deals every once in awhile, like this cool
French Military Police Jacket. I might get one, not sure yet. I did get a nice new
SP8 Survival Machete (gone up in price since I bought mine) and an awesome
Cold Weather Fleece Jacket Gen III (I'll use it as a liner, is Polartec, only 24.95) from them. Both items were shipped quick and are of excellent quality.
A surplus store here in Maine has a cool old truck, Mercedes I think, but they won't sell it.
