RE: Loss of rear air pressure
Gauge issue?
If it goes to zero, open the drain valve on each tank. If PSI, start looking for a sender/gauge issue.

RE: Cold Ambient Temps = Higher Alternator Voltage?
Yes, the intake heater grid can stay on after engine starting in very cold weather.
NORMAL.
If this continues for more than a few minutes after starting-- not normal.
Yes, in most cases but if it is extremely cold out, the grids will start cycling again if the truck is stopped and idling - even if it has been running hard for hours and is at full operating temps. It may also go to a high idle under those conditions.
Wow. The good news is that we have never been in cold enough conditions to have that happen.
So-- disclaimer: No idea what happens in well below freezing conditions, as that is when we head SOUTH.

RE: Tires exercised
You did the right thing, others may not know about the chemicals in tires that come to the surface to protect them.
Yup, you did the "best practices" route.

RE: Class A travel without interstates
Unless we are in a BIG hurry (rare), we often drive the back roads in our DP's.
U.S. 90 vs I 10 from San Antonio to Van Horn for example.

RE: US to require COVID Testing for International Flyers
It says you need to test negative 3 days before flying, so you would not be able to fly on shorter notice.
First, a "clicky": https://www.usatoday.com/story/travel/airline-news/2021/01/12/covid-test-required-international-passengers-flying-into-us/6640424002/
Wonder if that is WITHIN 3 days, rather than 3 days prior to flight? That would make more sense.

RE: Heart Interface converter/inverter/charger
Indeed, something is WRONG.
That inverter/charger should maintain "float level" voltage forever. Voltage depends on what you have programmed in (dip switches or remote panel). All the boats/RV's I have had with that unit over they years has done exactly that.

RE: Heater keeps dying
Are you plugged into shore power (to keep the batteries charged)?
The furnace runs on 12 VDC. Low voltage can impact operation.

RE: Interpreting Caster Alignment Specs
I would go for higher end of spec-- period.
So, perhaps 5 degrees left side, 5.5 degrees right side (difference to account for road crown)

RE: inspection
Someone familiar with what you are looking at (chassis, drive train as well as house) look over your potential next coach is one of the best investments you can make.
To make the experience worthwhile, YOU need to be there, wearing old clothes so you can "see what he sees". He can put your hands on that chaffed hose, can show you what electrical connections need to be cleaned/tightened.
There are many things that can not be covered in a written report. Without knowing your skill and interest level (vs I just right a check for it), he can not help guide you on what needs to be done right now/what can wait. What is within your skill set and interest level and what should be hired out.

RE: Cummins ISB 5.9 Cranks but no fire-ECM power.
I had a 95 Safari with the Cummins 5.9
And had to replace the injector pump, mine was the old mechanical style, lift pumps provide the volume of fuel from the tank, but the injection pump supplies the pressure needed turn that fuel into vapor when sprayed into the cylinder, I think you lack fuel, not enough going into the cylinder to properly combust,
My insufficient knowledge says the spray goes in to meet the hot compressed intake air already in the chamber, meaning lots of pressure is need from the injector pump, my memory might be faulty, need to hear from Wolf or other more knowledge diesel person
Very good. A slightly different way of looking at it:
The temperature needed for combustion (to cause an explosion when diesel is injected) is straight from the IDEAL GAS LAW. PV=nRT. With the diesel's high compression, high temperatures are reached as those molecules are made to live in 1/17 to 1/20 of their "normal" space.
And, rather than wanting high intake air temperatures, diesels are equipped with a CAC (Charge Air Cooler) as cool air is denser (more molecules per cylinder full). Then they "squeeze" those molecules to raise the temperature for combustion.
And, yup, most use a turbo to force even more molecules of air (oxygen is the important part) into the intake and cylinder.

RE: Is there any difference in DRIVING a gas class A vs diesel?
Gas engines now have transmission braking also
Yes modern transmissions in gasoline chassis now have the ability to downshift to give raise engine RPM to produce braking HP.
But, don't confuse it with a transmission brake= transmission retarder which has massively more braking HP.

RE: Cummins LP generator
Please tell us what year and model you have.
Is the propane regulator internal to the generator or outside?
Supplied from the tank liquid or vapor port?
How many hours on it?
When did it last run correctly?

RE: Border Restrictions Until Late December
However, US citizens can freely cross in both directions with no issues.
Based on the link, this sure seems contradictory to me.
Maybe a new definition to what is classified as "essential vs non-essential travel"???
And, assume this is referring to the U.S. Mexico border, not the U.S. Canada border (both were mentioned in the link).

RE: Burnt wires in power distribution panel
Odds are they are all loose or were before you tightened them. Loose connections = higher resistance = high temps = burnt wires.
I agree. MUCH more likely that a random power surge causing the excessive heat that destroyed the insulation on all of them.
Sorry, in my post one letter incorrect made my post on page one confusing/contradictory.
First sentence of my reply--I agreed with his conclusion (did then, still do!).
But, the "that" in the next sentence should have been "THAN", as "that" contradicts my agreeing with his statement. Thanks, fat fingers.
SO: Here is what my post should have said: "I agree. MUCH more likely THAN a random power surge causing the excessive heat that destroyed the insulation on all of them."
Again, sorry for the confusion.

RE: Air bags on a Class A gasser
We REALLY need to wait for the OP to tell us what chassis and coach they have.
Any other facts you have on your coach would assist in getting good answers: age, miles, what else has been changed on the suspension, axle weights, etc.
Barring that, we could give 10 suggestions that don't apply to their coach for every one who guessed correctly. Could lead you in circles!
