                                Here sre some images of bad element and it would be good idea to keep checking PH levels of your coolant mix to avoid such condition!

Chester, your coach is very close to mine ! in terms of build ( ours is #582 ) please check images of my sytem and model and I be glad to ask my repair person how to ajust it.

BTW, when we serviced our AH in September I noticed same situation , I looked around the radiator cap and noticed hose cracked and did not see at time coolant running out , but it did over time! i lost close to 2 gallons of coolant!
We replaced with longer hose and run it araound and in the back of the zones and out of the way,
I replaced hose and the radiator cap same time, its good to have spry bottle with soapy water and from time to time spry all the area around plumbing for any leaks!

Best,
