Looks like it's time for a new truck, as mine (that has long been paid off) is just giving me too much grief these days.. I'm looking at a Toyota Tundra, well two of them. Both 2006 models, one access cab and one full 4 door. The 4 door is much more feature rich.. Prices in the same genral vicinity, but the nicer one has more miles.. Like 40k more.. As always, these are "highway miles", which you see in every high mileage FS ad. Thing is with this one, they really are. I know the guy well. He drives 200 miles a day just to get to/from work.. So my question is, do you guys think "highway miles" are any different than I guess "city miles"?
