TYC makes radiators for several different companies. I think it's a foreign company, though, if you happen to have any preferences or feelings regarding that. The radiators themselves are pretty decent, though. I have an 11 year old 4runner and the radiator has a tranny cooler in it. They are known for breaking down over time and mixing coolant into the tranny fluid and trashing the transmission. So, I just ordered a TYC (Koyorad) replacement for it and will be installing it when it gets here. I have never replaced the one on my truck but the process for doing it on the 4runner is very straightforward and I'll be comfortable doing it myself. Based on what I've seen under the hood of my Ram, I don't think I'd have any discomfort changing out the radiator in it either. I think if you can remove the fan shroud and move it out of the way, the radiator can then just be unbolted from the supports and lift right out of there. Just be careful dropping a new one in to not let the fins get snagged on anything.
If you haven't already, go download a service manual for your truck. It will be helpful to you.
