Radiator Replaced 1999 Spartan Chassis , American Dream

I was cleaning my 1999 factory original radiator last season and noticed some of the fins between the tubes were rotted away. I kept using the coach as it never ran hot or overheated, waiting until I had time to replace it.

I started buying the parts last fall. I got a new radiator for a Volvo WG truck (2000 era) for around $600 from my local radiator supply. I also noticed the hard lines for the cooling system which were originally welded and painted tubing were quite rusty. My original plan was to remake all these tubes in stainless steel so I again put the project off until I had "time", LOL.
The crusty old rotting radiator kept nagging me, and with boating season and a new kitchen in the works I ended up buying replacement pipes from Spartan at a cost of about $1,100 for the 3 pieces.

This weekend was a rare one as we were not camping, boating, or travelling. So I tackled the replacement. I spent 1 day and the better part of Sunday to get it all wrapped up. WOW, the original radiator was way worse than I thought. Over 1/2 the fins were completely gone and the rest turned to dust if you touched them. You unfortunately cannot see much of the radiator when it's installed, we got extremely lucky, I still don't know how this rig never ran hot. The highest my scan tool displayed had been 200 degrees after a long 6% grade, normally it runs 181-184.

I took a bunch of pics of the install and the process, and somehow I deleted them. But, here are pics of the original radiator.
