After having gone through several Spectra Premium Brass CU850 radiators (could not get one shipped undamaged from several vendors including the NAPA branded version, Autozone and Rockauto.com, they are heavy and were never packaged well), I finally received one from Autozone which appeared that it would work.
Well, after 6 months it developed a leak on the joint for the lower radiator hose. The leak was a drip to begin with but eventually opened up to leaking several ounces of coolant at each stop.
After this I decided to try the aluminum APDI/PRO radiator. A lot less expensive and was it a good decision. The truck no longer leaks any fluids AND as an added benefit the truck heats up faster and gets hotter in the cold weather. I actually had warm and comfortable heat in the cabin in the cold weather we had just after installing it.

My next concern was cooling. Since I was getting great heat I was concerned that the radiator would not cool as well. We have now had a few days near 100F already this year and there was zero signs that the truck was getting too hot.
Hope this helps those looking for a decent replacement.
