LP usage
Recently purchased a 2017 Winnebago 31BE. How long could I expect my propane tank to last under these conditions; slide pulled in, small electric heater running, temp, 29 to 40, out in the open, heat...

Going from a ‘reverse engineering’ point of view, spec sheet says your Winnie has an 18 gallon tank, if your gauge is even roughly close, and assuming it really was full, you’ve used about 13 gallons. Winnie also lists your furnace as being a 32k BTU input unit. Propane is about 91k BTU per gallon.
So 13 gallons times 91k is about 1.2 million BTU, or about 37.5 hours of furnace run time, that’s about 7.5 hours a day for 5 days.
Does that sound about right to you?
I think the 18 gallons would be the water capacity and so a full fill would be 80% of that, or about 14-15 gallons. A little over half a tank would have been used (the gauge is calibrated to the full capacity, not to the usable capacity, typically), or maybe ten gallons. That works out to about 5.5 hours a day, or the furnace running ten to fifteen minutes per hour on average.
If going by a little three/four light gauge inside the RV, rather than the dial on the tank, the actual usage could be a lot different as those gauges cannot be very accurate even when operating at their best.
