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. WP-136 Vendor Meziere Enterprises, Inc.
