The leak is at the top and when I looked in the fill neck for the radiator I could still see coolant. From the looks of the leak area and down the radiator this leak isn't new. I have had to top off the radiator a few times but, just a little. Looks like the same situation for the ride home. I have a mechanic next door to the storage place that always does the jobs I don't want to do. I'll ask him to do the radiator. I feel pretty certain that I can get home OK. I have done a bunch of car radiators over the years but, never a motorhome.
It looks like the condensing coil will really be an issue getting the radiator out. And, I cant tell if I take the radiator out through the top or the bottom. I'll evaluate it when I get home. I will be running the heat as we did coming down as it was cold outside. I suspect that it will likely be a cold ride home. That's a good thing under the circumstances.
