Question - I read in another post that storing or leaving a propane tank on its side instead of standing up can also lead to loss of pressure. For our trip to Mt. Baker, I believe I actually did store the tanks on their sides in my RV storage box before standing them up for the fire. Any truth to this?

No loss of pressure. The cylinder is designed to operate upright so that no liquid propane is released through the normal port or the emergency release. There are cylinders designed to lay on their side... these are often used in a TC due to limited space.

At any rate, my question has been answered. I'll keep the Wave 6 mounted where it is with hose going outside to 20 lb propane tank. Crack a window and 1-2 open ceiling vents. Eventually, if I keep this RV long term or next RV, I'll look into attaching it to the RV propane line - though I do like the portability of my current solution.

Inside or outside, I really see no difference in outcome if my tanks blow up. I have 80 lbs of propane located directly under my bed in our 5th wheel "outside". Right where the manufacturer put it.
Inside there could be the chance of asphyxiation if there is a leak.

If you used it right away, or hooked it up right away there is a chance that that some liquid got mixed in the regulator, that could have effected stuff.

When my regulator froze up at 3AM i asked my wife to grab her hair dryer and go outside to thaw it. That’s how got that black eye. So now i use two wool socks on the regulator.

I used my TC for snowmobiling and used a 30# tank outside in addition to my onboard tanks.
At -30F I had a regulator freeze up on me stopping the gas flow into my camper. I thawed the regulator using a hair dryer and that kicked things back to life within minutes.

Since that one time, i now wrap wool insulation around the regulator only and use something to block the wind from hitting the tank and regulator directly.

I was told there is a diaphragm inside the regulator than can sometimes freeze up and sometimes crack. LP techs had to thaw regulators at the campground heated bathhouse as well. The tech told me it happens often enough during low temps and the right wind conditions. I always carry a spare regulator in case the diaphragm does crack. But that’s rare.

On travel trailers they usually have LP tank covers and are less likely to freeze up. But many other people packed their TT tank regulators with wool wraps just to play it safe.

LP tanks now have a float inside so only vapor can leave the tank.

I purchased and use the portable buddy which uses the 1 lb cylinder propane inside the RV. Works well except the little tanks last only about 4 hours on low. The portable buddy is made to be use in the inside with of course a vent open to allow fresh air. If using outside you can connect to a regular 20 lb tank. The little heater works quites well.
