Thanks again, everyone. All your comments helped me clearly understand the wiring involved, and now I have a good plan for when I go back to camp this Friday. The troubleshooting chart in the Coleman manual (provided earlier by Old-Biscuit) is now very clear. And it seems my earlier voltage test at the thermostat might not have been valid. So I'll start by checking for 12 VDC between the white and blue wires at the thermostat, and go from there, just like the chart says. I'll update again this weekend.
