You'll need to define "hog" for me to answer that part.
If you're referring to acceleration, I don't know what my '96 7.3L's 0-60 mph performance is. I do know that I accelerate and climb mountains at partial throttle even though the F250 is maxed out GVWR- and GVCWR-wise rigged for camping, so I've never felt under-powered. This is probably because I realize I'm driving a house on wheels, and I don't expect it to perform like the Z-28 I used to own that could do 0-60 in less than five seconds and reach 150 mph or more. I expect my RV to perform closer to the 18-wheeler that manages to haul the freight for a million miles but can't accelerate with the small vehicles.
As far as my horsepower, it's rated by the factory at 215, which was the leader-of-the-pack in 1996. Measured at the wheels, it very well could be near 170. And today, it very well may be considered a "hog" acceleration-wise compared with the new 400 hp diesels being put out on the market. But it's not a hog when considering what it "eats": an average of about 15 mpg on the long runs I make. Without the RV, I achieve 23 mpg at 55 mph and 21 mpg at 70, as calculated by miles driven and fuel pumped.
Besides the normal consumables, the only mechanical pieces I've had to change on my rig so far are the radiator and water pump. So far, my ole F250 has been a stellar investment when considering the overall financial outlay of purchase and maintenance. I can't think of a rig that would have given me more for the buck. So I can't consider it a hog in that regard either.
Well, I've beat that hog to death, so I'll stop now.
