Use the Chevy Trailblazer Race Truck, give it a turbocharger, and convert it to 4x4, It will go to 140mph in 6 seconds.

The Dodge Dakota Club Cab (4WD) is a good truck to use in the game.

Use the Ford F-150 Race Truck equipped with sport fly wheel, turbo charger, dyno tune levels 1-4, forced induction exhaust and a high capacity fuel pump.

If you like to offroad, put in the "$1 million" code and get the Ford Excursion. The F-250 has the same amount of power but the rear wheels spin a lot.

Use the Ford F-250 Supercab 4x4 with race fly wheel, race clutch, race gear box ,race ignition system, dyno tune 1, race exhaust, and race headers. It will do 0 to 120 in six seconds and is an excellent jumper.
