Thanks for all the info guys...
I think W_S nailed it. We all have things we're good at in life, and things we're not. I love cars, but I'm no auto mechanic. I know I could learn - but I've never gotten any satisfaction out of fixing a car. Every time I've ever done my own auto work, I've always walked away feeling like it was a waste of time and frustration, and often money as well that I could have saved myself if I just brought the thing to someone who knew what they were doing and had all the tools and parts they needed, and wrote them a check. I can see the obvious stuff, but I can't identify the difference between a truck runs great now and will die 10 years, vs one that runs great now and will die in 10 months. I can't put an exact figure on how much money I will save in buying a car from someone I know and trust, who knows the car, and who knows how to fix it and would be inclined to help if that's required. But I do have an estimate...
About a year ago, my friend had advised a neighbor on his beater truck purchase... The neighbor had found a late 90's-ish Ram 1500 for a few thousand dollars and thought it looked good, but my buddy looked at it and told him not to buy it. I don't know what the specifics of that conversation were... But I do know the guy bought the truck anyway, and things were pretty good for a while. One minor electrical thing right away, but then several months of decent service. Hauled all his firewood with it this summer... And since September, the guy has sunk about $8K into replacing the engine, then the transmission, then repairing several electrical issues, and now the front end has gone bad and he's got no 4x4. Looking at an axle swap or something to that effect to repair it. He hadn't thought to ask if the truck had an LSD, so now it's finally started snowing and the guy's got a $12,000 1998 1WD Dodge Ram 1500 with a freshly rebuilt engine and transmission. I know more about cars than that guy does... But most of that is knowing that I don't know enough to guarantee avoiding a similar situation (aside from not spending more money to fix it than it would cost to just buy something else).
I think I'm going to put my money on the equity in my friendship with the guy who does know what he's doing, rather than on a particular benefit of detriment of a specific unknown vehicle. The samurai should run for a long time. It's small, light, and easy to recover if I manage to get it stuck. I don't want a rock crawler... I actually more or less hate 4 wheeling and can't for the life of me figure why someone would do it for fun. I just want to be able to drive anywhere around my house when I need to without dropping the plow or taking the chains off my truck. In the unlikely event I actually need to drive it for any distance, it will be uncomfortable and slow, but it'll get me there. It'll be a few weeks probably before I get it, but I'll post some pics when I do.
Thanks again for everyone's advice.
Edit: this isn't the one, but it's pretty similar except for the smaller wheels...
