Wow, thanks for all of the replies! It's so nice to be able to ask a question and get a bunch of answers. I have thought about the t-5 swap, and it would be nice, but I think that I want a little more 'truck' in my truck. I also plan on getting my 235 built up in the next year or two. The NV4500 is a stout piece of hardware and seems to make more sense than a lighter duty transmission. I also like that I would be able to still have a compund low first gear. The two things that I want to have in my truck are workability and driveability. The 4500 would give me an overdrive for the highway and a low gear for working and hauling. Thanks for the help, I will get to work on figuring this project out.
