I can tell you that when the heater core on my Journey failed, I talked to a local radiator shop who would build a new core for me. However, the cost was significantly higher than the OEM core from SCS Frigette.

Smlranger Thanks that is what I've been thinking.In all probably a local built core even at a significantly higher price is probably better than the Winnebago replacements.It seems that quite a few Winn. heater cores have been replaced multiple times.
I haven't done it yet, I'm just trying to get the parts together first. I thought I had read on this forum a while back that someone had replaced the core on this unit.It explained how to do it along with an after market core.
Some years ago I replaced the heater core on my Southwind. I took it to a local shop and got the original re-cored for a small fraction of a new one from Fleetwood. The guy at the radiator shop talked me into replacing the heater type honeycomb core with a core similar to the main radiator, It worked very well and I had the motorhome for another 12 years with out another problem.
