I paid $1700 for my 5000, ran like crap, no bed, cab was a mess inside (mice), no passenger door guts, bad brake system, the front end was way out of whack ETC. But the cab, sheet metal and frame are solid.
Myself, I think that LCF is worth up to $1800 especially if it just needs a good cleaning and mechanical going through. And assuming the tires still hold air, I wouldn'tve bought mine if they didn't...
Before and after about $4000 invested between bed, aux trans, and misc. parts.
