UPDATE:
I called Bilstein first. They told me about their B8 5100 series shocks, how they're monotube, and how they're great on a pretty stock diesel. PN's for stock to stock+2" B8 5100 shocks: 24-185776 front, 24-191203 rear.
What I didn't like is their limited lifetime warranty does not cover oil leaking, normal wear and tear, or rust.

I then called Rancho (Tenneco, and also does Monroe fyi). They recommended I not get the 7000 series shock since it's valved really stiff for pre-runner ish driving. He said if I don't see myself going fast off-road, I'd be happier with the 5000 series and it's going to give me plenty of performance for DDing and towing. The 7000 is monotube and the 5000 is twin tube, but mounted in a vertical orientation, it shouldn't matter. The new 5000x now has a nitrogen charge as well.
RS7000MT PN's: RS7044 front, RS7269 rear
RS5000X PN's: RS55044 front, RS55269 rear
What I really liked is their limited lifetime warranty covers anything that would cause the shock to not work, other than bending it in half from misuse. They said if oil ever escapes, even if it's 15 years down the line, it's covered. If the piston ever rusts, and it causes a performance issue (like oil escaping or seals tearing) it's covered. And in the first 90 days, if I don't like them, they'll refund me and pay up to $50 per axle based on labor.
They also recommended, if I'm worried about finish in the rust belt, to spray the body with a really thick layer of clear, or use that 3M clear sticker stuff. They weren't worried about the paint they used, but were more concerned that a rock chip would leave an area unprotected.
So... I'm definitely going to go with Rancho, especially since comparing the 7000 series and the Bilstein 5100 series, they're almost the exact same price and the 5000's are cheaper. I just need to do some reading on if I want the 7000's or not. They sound better to me, but the guy on the phone sure sounded like he knew his stuff pretty well. I played dumb and let him talk and he was not just some sales guy.
I'll keep you guys updated!
