I'm Awesome
It would be a mistake to install hose where double-wall seamless steel tubing works just fine.
I have a 40k# cooler that I bought for it that's not installed yet.
I currently have the stock radiator cooler, stock aux cooler, and an aftermarket ahc cooler. The aftermarket aux cooler is just rubber hose to Barb's and is janky as ****. I had one line blow off on me already, which may or may not have been my fault
I have a ton of time into researching this. My dad usually has to replace one or two cooler lines every year in at least one of the plow trucks in his fleet. Granted, those endure more winter weather than mine hopefully ever will, but the general consensus on pretty much every forum that I've read online says that -an swap for oil/trans hoses are far superior to the stock lines if done correctly with quality parts.
I also thought about doing the oil cooler line since I will probably have left over hose. I've actually been procrastinating because it seems like a giant pain in the ass. I figured I'd wait until winter
