Yup, as an example, two 220 ah 6 VDC batteries wired in series= 220 ah at 12 VDC.

It will not know or care. The wired from the battery bank to inverter/charger IS wired 12 VDC. Said another way, two 6 VDC batteries wired in series are EXACTLY THE SAME as a 12 VDC battery.

Actually, a plug-in digital voltmeter IS YOUR FRIEND. Plug it into any 120 VAC outlet and tell at a glance if voltage is adequate. No reason to ASSUME either way. Lots of choices, some that will also show polarity and ground. https://www.amazon.com/Prime-Products-12-4058-Power-Monitor/dp/B000BRFTH6

MAYBE. Turn off everything else (like battery charger, refrigerator to propane, etc) Plug in. Turn on A/C while watching voltage. If above 108 VDC you should be OK. The MAYBE part comes in because we don't know the size of the wiring in the house and the length of the run from breaker box. Smaller gauge wire and longer run could make voltage dangerously low.

Yup, a pictures with dimensions would make finding a suitable replacement much easier.

Assuming the "default setting" for the Schumacher charger is WET CELL, that is close enough to the charge parameter of the AGM that this would NOT be the cause of the battery issue.

The symptoms STRONGLY suggest an electrical issue (rapid cycling from low to high PSI-- far faster than could occur with load/compressor). So, I would start with cleaning/tightening the electrical connections before cutting into the air system.

Yes, GREAT KISS solution.

What chassis? Sure sounds like a bad connection between sender and alarm or bad sender.

After several years of experience with "smaller vehicles", I agree.

Eddy, Welcome to the FMCA Forum. Please tell us what coach/chassis you have so we may be of assistance. What leveling system do you have? Is it not leveling properly when parked/leveled or in travel mode?

Have you downloaded the Cummins computer checking for stored codes?

Yes, on the 8 outboard air bag suspensions, you need to verify if the ride height is measured on the front or rear bags/in front of or behind the wheel. I know on Foretravel 8 bags, you measure ride height on the bags TOWARD THE CENTER OF THE COACH= front of rear and rear of front.

alford316, Welcome to the FMCA Forum. Assume your chassis has two ride height valves in the rear and one in front. First, a question. Can you access the rear ride height valves from outside the coach or do you have to crawl under? If from outside, at least the first adjustment (rears) requires no safety stands. For the front (again, assuming one in the center of the coach) you absolutely need safety stands. Only exception is to let all the air out of the suspension and verify that you can still safely crawl under the coach. Yes, on some you can (some coaches and some "body thicknesses"). Another alternatives to safety stands is to drive all wheels up on 2X10's (still level) and verify that you have safe room with all the air out of the suspension.

Check battery voltage. If below 12 VDC, you can chase a lot of codes. So bad batteries, loose or corroded connections, etc.

With your Cummins diesel engine (assume ISC), use the DOWN ARROW to select a gear where you can keep RPM in the 2100-2300 range and use a little less than full throttle. The higher RPM turns the water pump faster and on most, also turn the fan for CAC and radiator faster. Use of Power or Economy mode still leaves the transmission in "automatic mode". The down/up arrows allow YOU, the driver to select the proper gear.

Yup, if we know what coach/chassis you have, we can give advice on remedies for overheating.

DonDuddy, Welcome to the FMCA forum. Please check again for your chassis, VERY unlikely to be Workhorse. Also, what brand jacks do you have? Model?

Heather, Call around to RV dealers and find one who can test the refrigerator PC board. The flame is now the way is should be (much higher flame/more BTU's than with the old burner tube).

Ron, A multi part answer: Doubt you will damage the hitch as long as the toad brake is off, etc. Guess if a really severe angle, it could do damage, but the hitch is designed for a lot more "jerk and pull" loads while driving than you will expose it to parked. But, if you are boondocking in a parking lot, lowering the jacks and extending the slides is often viewed as quite different from just overnighting "buttoned up". Also, if on asphalt, you will very likely damage the parking surface with the jacks-- so you will need to put boards under them to spread the load.

So, will the conversion be to 1 ride height valve in back and two in front OR one for each wheel position. If the latter, would appreciate a write up on what Freightliner is suggesting.

DougPeyton, Welcome to the FMCA Forum. Go to their manual and look up their definition of "SEALED BATTERY". Suspect that is an AGM. Much more likely than either GEL OR FLOODED.

With the burner tube removed, you can visually tell if it has deposits in it. But, the slit dimensions are important for burner function-- that is why I recommended replacement.
