I think the Bilsteins are an excellent shock as well, they are highly rated on the other forum I belong to (cumminsforum). I, however, went with an Edelbrock Performer IAS set of shocks for my Dodge Ram. They were a little less expensive, offer a very good ride and performance, and are made in the good ole U.S.A.
Story behind it - I was talking "Trucks" with a fellow camper who was pulling a 30+ foot 5th wheel with a Chevy 2500 Diesel pickup and I mentioned that I needed to replace my stock shocks. He said that he chose these after researching many of the other name brands and comparing them to the Edelbrocks. He then made a phone call to the manufacturer and at some point, he was able to speak to one of the engineers behind this particular shock. Since he is an engineer as well, they talked "shop" and got behind all the physics of the design and whatnot and well, there ya go. If they are good enough for him and his application, I trust his research and decided to go for it as well. I'm pulling just an 18' Hybrid, but I am very satisfied with the ride with or without the TT on the hitch. Don't know if my rambling helps any or not, but thought I could put 2 cents in the can here....
