Hey all I'm looking at possibly purchasing a 98 1ton with the 6.5 and the nv4500 and I was wondering if you can give me some info and advice on what to look for when it comes to this drivetrain combo. Fuel mileage, longevity, mods/upgrades for better efficiency, etc. I know that this "underpowered" compared to a dmax but I'm fine with that (I get in too much trouble wit too much power )
