It can be done, I did 941 with a single but for me it is not worth the extra expense to simply prove a point. Pretty much decided to put a 6.7 PSD in Snow White, I can have 1500hp for half the price of a 1000 in a 7.3.
Truck runs and drives great, good tread on tires, inspected and tagged, 306000, replaced injectors recently with AC single shots, Garrett GTP38R turbo and fresh rebuild on transmission Transgo tugger and PI TC.
Simplicity, anything I need suspension/steering replacement wise I simply buy for an 05, no special parts or work needed.
Also IF someone wanted to do a suspension lift later just buy for 05 truck and ALL parts bolt on.
