Could the drivershaft require lubing in addition to your hesitation?
If I found the same deal I'd be all over it.
Frame is rust free. The hitch has rust on it for some reason but the frame is pretty solid. 3400 is the cheapest I have seen here in C0, I have seen 4Runners with almost 300K miles posted for well over 4K. With the E-locker to me seems like a pretty good deal. The timing belt service was done 4 months which is a nice thing. Just have to do the major tune up soon on it.
I was just talking to a co-worker today who has a cabin out there and she said CO has laws against road salt? Yinz use magenisum oxide?
