hehe...Probably not that mod. But in general jacking up a rig and changing axles and gears from stock does reduce the resale value compared with a stock vehicle in the same condition, at least when it gets traded in or sold back to a stealership. Maybe not in a market like yours where there is great demand for built rigs and many knowledgable buyers, but most places it does. Just guessing as to why, but the quality of parts and workmanship is unknown, what other problems have been created is unknown, and that stuff can be a liability. How about that full locker - the stealership doesn't know someone's put it in there, 18 year old kid buys it, stomps the skinney turning onto a wet road...180* into oncoming traffic. I think a good lawyer would have a field day with that one.
