I'll probably just crunch the numbers and compare a full brake job with factory replacement parts vs a full job with the upgrade and see how much more it may run me. My truck has relatively low miles for it's age at 155k but new calipers may be good to go ahead and upgrade while I'm in there.
I can say I have hauled some pretty heavy stuff (maybe a little too heavy at times) with my truck and never had a problem with it stopping as long as your aware of it and give yourself plenty of stopping room. The 4 piston setup would definitely be an upgrade worth it if the price is not unreasonable. I did all four brakes on my truck last year but I don't remember the exact cost of it. I know since buying this truck with 100,000 miles on it, and it now having a little over 300,000, I have replaced both front calipers and believe they only cost around $75 a piece. If you do the upgrade please post back as your have my curiosity now too on how much difference it will make.
