I see several possible advantages to the dual pump setup.  Maybe I can
turn one off for curise which would save current draw.  A spare pump
would cost about 1/2.  Redundancy, which is always a good thing.
Plumbing might actually be simpler since I have two radiators.  The only
downsides I see is weight, space and check valves. I finally found the
WP-136 on Summit. thier PN has an S on the end.  It looks like the
current draw is 1/2 of the WP-337 if I'm to believe the mfg.

OK, I've made the decision, it will be two WP-136's.
