Why yes, I purchased a ~4yo truck with nearly 100K miles on it. And yes, outside of eating manifolds it has required only the usual stuff (breaks, shocks, tires, oil & other fluids). Over the last (I guess) 14yrs I've only put ~25-30K miles on it - barely over 2000 miles a year. I don't expect to put to much more miles per year on any newer truck.
I own a Northern Lite - so fully loaded I'm rolling ~10K+ (depending on how much fire wood I'm carrying+ other stuff). Sometimes I'm pushing ~12K.
I think my current truck has 4.12 gears pushed by a fuel injected 351C. 2nd gear @ 40-50MPH going over mountain passes is not fun. I don't drive over 60MPH (unless passing). I'm getting ~6-8MPG.
I read somewhere that the new 6.2L gas engines are pushing nearly 400HP. That seems attractive. I'm sorry I got confused with the V8/V10's and did not realize that they stopped offering the V10 in the F350 anymore.
I'm seeing V10's with 100-250K in my local area. Recently saw two different 2008's with less than 100K miles on them. Considering that I'll likely never put more than ~30K on a newer truck I'm targeting gas'ers with less than 110K miles.
The older 7.3's are really going for a "song", I've seen a number of them with less than 200K miles in the < $15K price point. A friend who still has his claims 16MPG with his camper loaded (flat ground, cruse control).
I'd really like the 6 speed tranny, then again there is a BUNCH of stuff "I'd like" but not enough to drop ~35-40K on a new truck. :)
Damn FORD keeps changing the HUB/RIM offsets so to keep my Toyo 608Z's I'll have to invest in yet another set of Vision Hauler Rims. (and try to unload the ones that fit the 97') (sigh)
Out west you have to think of RANGE between fill-ups.
So new 6.2L ~$35-40K or older 6.8 ~$10-20K.
