I'd like this idea, since it would give a purpose to caravans.
BUT im not for the un-lootable caravan leader.

Just an idea, but maybe you could trade with them via dialog?
Like the trappers around Redding, that sell gecko hides.
They could have 1-4 different items for sale, hunting rifles, brahmin hides, water bags... ect
And since they do alot of trading, perhaps at rare times they might have something
of value. (Laser rifles, Sniper rifles, M60's ect)
Or something of rarety (LE BB Gun, EMP nades perhaps?)
Although stock would depend on which caravans...
Redding may have Gold nuggets, New Reno would have Jet, or other drugs.
Once you buy an item from them, they will no longer have it. Certain items may be more than 1 in stock, and weapons/armor would come with random det % and break count. And overpriced
Just a thought.
