Wow! I can't believe you guys dug this thread up! I did go into an F350. I also got the 5er raised approx. 3.5 inches to give me a perfectly level ride with 8" of clearance using a B@W Companion with the factory puck system. The new truck is awesome. I am very glad I went into the 1ton and putting the subframe lift on the 5er was no biggie. I found a welding shop that specializes in subframe lifts among other things and they did the entire job for 700.00!
Here are a few pics from my other post:
