I get it, I'm a hot rodder, there's a '55 Chevy with dual quads and a four speed in my garage... but I'll echo what a few other wise guys (ok that came out wrong haha) said. You'll stress the heck out of that truck. The supercharger will rock when the truck is empty and all that power is easily converted into GO. When you're loaded up heavy, all that power will break stuff.
Get a diesel if you want to fly under a heavy load! And turbo diesels are a hot rodder's dream! It's so easy to turn the power up to ludicrous levels your gas motor could never handle!
My '99 Cummins was a dog. A few simple things, and now it's a monster my old Ford with a very hot-rodded '68 428 could never keep up with, pulling weight up a hill.
You can have 600HP with a turbo diesel too - but the HUGE difference is the 600HP diesel will have 1200 ft/lbs of torque, at a useable RPM, and it can run at heavy throttle under a load for an extended period without blowing up.
How embarrassed and annoyed are your going to be when you hit the hills in your newly supercharged, bad-*** truck and some guy in a pumped-up diesel pulling an apartment complex blows by like you're a '67 VW Microbus while you're at 6000 RPM and getting hot?
Come to the dark side.
