Its been done before.
The thing with those leveling kits is that they are hard on suspension parts. You'll eat up ball joints faster. They should work just fine on your truck though. You would need to have a bigger lift before you come across vibrations.
I work in the oil patch as well, this winter one of the bosses on a project I was on had a Harley Davidson F150 as his company truck, and the only thing he did was get a set of 20" wheels from an FX4 and put a good set of tires on them and swap to those while he was working. He didn't seem to have any trouble making it everywere anyone else was going, and then when he was back in the city for time off he just switched back to his Harley Wheels. Thats one thing to consider.
Your not putting a Welder and a bunch of welding tools in the box are you? Cause you might need a helper leaf or some air bags if thats the plan.
Hope that helps you.
