Propane tanks...20 or 30 pounds??

A lot is a relative term. If it is cool, the furnace does not run much, and propane use is not too bad. If it is in the single-digits, the furnace runs a lot and will go through a tank quickly. There are ways to reduce the use. When not there, turn the thermostat down. Likewise at night, turn it down while you sleep and use additional blankets or quilts to keep warm or use a sleeping bag. In the morning, turn it up. If you don't think you have to keep the interior at 72 degrees F. all the time, you can cut the propane use to a reasonable amount.

Yes, if shore power is available, a ceramic block heater is good. We did not get a chance to try one when we were in our R-Pod in 4 degree weather to see if it would have been adequate because we did not have shore power to do so. After our accident, I was able to plug into a 15A outlet, but I did not feel it would have been proper to use an electric heater when the tow yard operator was gracious enough to let us stay the weekend in our 'Pod. We had purchased a Mr. Heater Little Buddy heater. It was adequate to help heat, but was too top heavy, so when I had a chance, it got returned and we bought a Mr. Buddy Portable heater. It is definitely more than adequate for the space and is more stable than the Little Buddy since it has a much wider base. If there had been a way to stabilize the Little Buddy, I would have preferred it because the size is smaller and the output is adequate. Any gas heater like the Mr. Buddy models or catalytic models does require ventilation both to avoid too much moisture build-up and to avoid CO buildup. What makes them more efficient is that they are not venting heat outside like the furnace. If the RV furnace could be made more efficient, it would be nice. However, that would likely make it so big and so expensive that it would be cost-prohibitive to install in any but a luxury RV that sells for many multiples of what we pay for an R-Pod.

Works great. https://www.amazon.com/s/ref=nb_sb_ss_i_3_15/146-2805682-4862748?url=search-alias%3Daps&field-keywords=dometic+propane+level+checker&sprefix=dometic+propane%2Caps%2C306&crid=210PHNI0MSNVU I think I need one.  More for my grill and smoker.

Mine  came today and seems to work fine.  The tank on the smoker is empty, the grill is nearly empty, and the pod is nearly full.  Seems well made and so far I am pleased.

Originally posted by TheBum We've been using this one for several months. We can check the level without even leaving the Pod. https://www.amazon.com/Products-024-1001-Propane-Level-Indicator/dp/B01C5RQJHS/ It's the same as the one rawest50 posted but without the monitor; we use the free iOS app instead. It works the same as the handheld one above except that the sound waves emanate from the bottom of the tank and reflect off the top surface of the LP, thereby measuring depth. The level will change with temperature because the liquid expands and retracts, but that's the case with most gauges.

I have not emptied our tank so that is why I am wondering. I plan to put it to use on our trip to Kentucky just to make sure it is reading correctly. Should be cool enough to use the Pod heater. I can use electric as a backup if it runs out.

How much have you used you gas? Cooking and heating.

Originally posted by Tars Tarkas I like dual 20s because you can still have propane heat, etc, while you go get the empty filled.  TT

When one is out you know you have one full tank left. Get the empty re-filled and back in business with two. Good way to make sure you do not get caught off guard.
