Ugh. Ok, what SHOULD one use on the manifold bolts?
thanks,

Karen,
Does the coach have an oxygen sensor?
Can you put the anti-sieze where it cannot possibly get into the exhaust stream?
If answer to #1 is no and/or the answer to #2 is yes, then use the copper based C5a (I like it better than the nickel, but that may just be the result of using it for over 40 years).
