3K trip over 2 weeks, should I do this service or wait

[mbrund]

So in a 1992 WB40, the Primus antifreeze is also part of the cooling
system? For some reason I thought they where seperate systems and
used a heat exchanger between them. I will go out and fire up the
coach now and run all the systems so the fluid gets circulated as I
am going to town in a little bit to pickup test strips to test the
balance.
