RE: Sonic Boom
I just remembered this music track..
https://youtu.be/BcqtZethvxw
Alas the digitizer that digitized it did not do a good job on the end of the piece (My memory is of an analog recording much louder on the loudenboomer)

RE: 12 volt fridge in TT
There are basically 4 types of 12 vole "Fridge"
One is an absorption unit,. these are often 3-way (12 120 Propane) and really kill batteries when on 12 (20 amps or more draw)
One is a traditional Compressor... also about 20 amps running
one is a high effiency compressor 3-4 amps running
One is ... Well 7-010 amps running but no compressor in fact other than a fan no moving parts. Doubtful you have that kind.

RE: What is the lowest voltage you have seen?
The thing about low voltages and electrioncs.
THough in days of old when folks were bold there were Radios and the like that actually operated on 120 volts rectified direcr. NO TRANSFORMNER actual line power and if you plugged the plug in and touched the chassis.. Depending on which way the plug (2 blade) was turned.. ZAPP... (you got bit) thankfully you don't see those any more save in vintage stuff. I mean very vintage .
Toay most everything runs on much lower voltages. and a Power supply converts 120 volt AC down to 4 or 12 or something DC. (Those are very common voltages One brand I know uses 14 volt)
THere are basically 3 types of power supplies.
Switching supplies.. If you fed one of those oh say 20 vols AC.. i should be able to deliver 12 VDC all day at full output and not overheat... OR you can feed it 250 volts. . And it will still output 12 VDC and not overheat.. It truly does not care so long as you are feeding it at least about 8 volts AC or more .
Transformer supplies There are types
Regulated SHUNT.. A lower supply voltagte they run cooler
Regulated PASS Same thing
Non Regulated or ferroresonant These may not deliver full output if the voltage drops. Many wal wart are of this type (Low power like phone chargers)
They also will not oveheat.

RE: Is replacing the furnace worth it?
I do not think the new furnaces are all that much different in terms of battery drain.... But if you only park where you have decent electric a Ceramic type Space hearer is compact and operates at a lower temp than the hot wire type. >DO however make sure the tip over switch functions properly. If you often park w/o reliable electricity. (and from the battery draw question I suspect you do) disregard that part of this post.

RE: Just curious
What do you do in your free time? For example, I learn something new for myself and read a lot of books. Now my hobby is astrology and mysticism
Well.. LIke you I read. and read and read and read.. If I'm reading cozy mysteries it's not unusual to do one a day in fact in the last week I think I did 5 (couple of days I was busy with other stuff)
I'm also a ham radio operator and chat with folks all over the place. Though I'm antenna limited and thus only use VHF/UHF for the most part (I do have HF gear but it is a pain to use in my car and then I have to take the antenna down before driving) But with D-Star and a few other advanced modern ham radio VoIP stuff... Well I'm in Michigan and just now the Net Control station is a tad S.W. of Little Rock, AR.

RE: Voltage protector 110V?
Progressive Industries HW-30 is a hard wired 30 amp version of this with several advanced features and a remote display.. Hard wired beats plug in.
Southwire/TRC also makes one that is like the HW-30C I used the 50 amp Southwire version. Very nice.

RE: Water heater Anode
What is the make and model of the water heater?
There are exceptions but GENERALLY
Suburban has an anode. this is properly called a sacrificial anode. it's job is to sacrifice itself to protect the tank from "Rusting" (Corroding) out.
Atwood.. usually does not. This is because the tank is made of a different metal that is resistant to corrosion
NOW: some folks will put the spigot in the atwood... Differing types of metal (The brass of the spigot and the metal of tank) Tend to corrode .

RE: Water pump sucking air
Suspects: Clogged outlet strainer on tank (this.. if it exists.. Is inside the tank. I found mine when I unscrewed the fitting from the outlet and that is how you remove it for cleaning)
Valve closed that should be open (Not all rigs have this valve)
Valve open that should be closed (Drain on my rig was "T"ed into the pump inlet line)
Hole in tank to pump (Pump inlet) line
Bad pump
Oh and the famous EMPTY TANK
That's the list.. Good luck List (Save for empty tank) is in Flow order.. Not suspect order)

RE: Dometic FRig operation
Good morning. Learning my new systems. Frig has three modes; gas electric; and auto. If my generator runs out of gas while on ac mode, will it default back to propane? Doing some driveway camping to become familiar with all the new onboard gadgets. It's goin gto be different than the old "88" C.
To answer your question.
You can LOCK it on Gas or Electric and I sometimes did lock mine on gas for one reason or another. And if you do it will not switch.
But if the AUTO light is lit.. then yes. if the generator stops for any reason it switches to gas. Or at least tries to (If you are out of propane then it can not). Still needs 12 volts however.

RE: Honda 2200i travel
Not sure about oil but if the crankcase is vented the vent will be high enough it won't slosh out if upright.
Gas tank is sealed.. in fact true story... Campground used some 2000i generators for a halloween thing.. One at the station where I was kept stalling... They forgot to open the tank vent (A knob in the center of the gas cap).

RE: Sorta tells it all, don't it.
Close cover before striking match.
Actually we have had a sort of flying car since the 1950's The wings detached and were stowed on a trailer towed behind the car.... There was a TV show where the star flew one that he actually owned... (Bob Cummings???) Also they made one for one of the Bond movies. this one was different. not nearly as nice.

RE: Remote measurement of fridge and freezer temperatures
The problem with battery operated RF remote sensors in the fridge and espically in the freezer is .. The batteries tend to not work. (And the frequency may drift)
Beyond that I can not say much.... Now designing a sensor.. It's easier than you think.. inside that Accurite is a small blob known as a thermisistor.. You need to remove it and "remote" it. (Add leads) then route the wires (There is already a path as there's already a thermisistor inside the fridge and a water line into the freezer) and hook the leads back to the sender OUTSIDE where it's warmer.
Alas.... I can not help you there. You will very likely destroy the thermistor (They are cheap but I know not the value> How cheap. oh 10 bucks for half a dozen give or take)
If they are the right value.... Well 3-D printers tend to eat 'em.

RE: Awning not working right
If that unit works the way I think it does (I had one) the controller is current sensitive.. That means you press the button and the motor starts to trun. when the motor suddenly draws more current (indicating it's not turning) the unit shuts off.
Something may be overloading the motor.. first step is to inspect the awning to insure it's rolling and unrolling smoothly.. also check the gas shocks to insure they are not binding.. finally Lubricate.

RE: No power to inverter
One thing I will warn you about.. on the inverter.. if it's like Mine. like inverter the wire leads all (Both 12 and 120 volt) connect in apanel in what I call the REAR (opposite the fan)... and there is a fuse.

RE: How do you measure the ambient temperature?
Well there are proper ways and normal ways
Standard method is an outside thermometer You can set it on the picnic table but make sure it's in the shade.
If you want to get "Fancy" design a "pagoda" type house to set over it. Good ventilation and fully shaded so it's not reading sunlight.
Now there are lots of proper "Shells" for outside thermometers.
Oh. you can get one of the wireless types so you can read the outside temp. from inside...
Just make sure it's out of the sun and has good ventilation around it.

RE: Motorhomes with 19.5 vs 22.5 tires
I don't know about handling but the larger tires can carry a larger weight load and will last longer (miles) due to fewer revolutions per mile.. They also cost more (naturally) but I'd go with the 22.5s

RE: Heated mat?
Have used electric heat a lot. works well but you need to be cautious about setting heaters in areas where they might cause fires... Ceramic types put out the heat just fine but do not get as hot over all (more surface area at a lower temp = same amount of heat) than the older glowing wire units. Oil Filled are larger and thus a problem on their own.
I also have one with a remote thermostat.. That one works very nice.
You can but a remote (plug in) thermostat at amazon and on the heater itself just crank it up to max. Google: plug in thermostat for space heater
