I have been roaming the diesel web sites since 2001,at which point I bought the the 2002 DMAX, you will see many posts of increased HP boasting, then you will come across the the odd post (my truck wont start or quite at a traffic light) , you will most likely find the owner has added an electronic HP increaser, thats fine so long as it a play thing rather than a WORK HORSE. For a reliable WORK HORSE ,
have the engine oil analized
put synthetics in drivetrain front end, tranny, transfer case, rear end,
keep original air filter (as per testing done on this web site)
add another inline fuel filter
get a bigger fuel tank (best improvement I have made)
time to change your universals if you tow a lot
change the antifreeze (5 years)
add bilestin shocks
4 new REVOS
you have 200,000 mile warranty on fuel injectors
From all the reading I've done the 2002 DMAX is probably the best buy out there, good fuel milage, lots of torque,
a trade is going to cost 20,000 to $30,000 for that money you can get a suncoast tranny and a new engine any time you want,
drive safe
good luck
