Getting the rig cleaned up for trip and visit from family the first week of August.

You don't need help, DW already gave it to you.
-
There also should be a check valve to hold the vacuum to the HVAC system when accelerating. Even with a good check valve a leak can also be the source of failure.
-
DW already spotted them and she wants a orange 4 door.

Don't you hate when somebody breaks something and you have to figure out what he did?

Appears that OP got no help at all. Vacuum leak or check valve is first thought has nothing to do with spark plugs or Catalytic Converter. Please find where vacuum line comes through the firewall and trace to leak or check valve in both direction.

Does it do the same when running generator?
-
Vacuum leak, no reserve.

I had to replace a gearbox for the same reason on 2006 HR. The worm gear worn out as it was made out of brass.

What year is your coach and does it have a tag axle?
-
For my Spartran chassis the cap makes it easy to check the oil level in the front and tag hub. For all wheels including dual rear you have to remove nut and large cap before removing wheels.

Good deal, if it was a car or light truck 1234yf would be what it have.

Yes it would work but lots of cars would have flaming crashes.

4 hours ago, DickandLois said:Ray, The 2 Freon's are compatible. The difference is price and 1234yf is flammable. Because of the molecular structure the compressors tend to run cooler, but a spark can light the 1234yf. Not much of an issue in Diesel coaches, but I do wonder about gas powered vehicles as the ignition systems age. There is a flammability warning in the safety data sheet. Some AC Compressor builders are using a different PAG oil for the 1234yf.
Rich.
When I got certified on the new refrigerant we also had a class and a test to be certified. If you top off a A/C unit with r134a in a r1234yf unit you contaminate the system which is illegal.
Please read number 6 in the link.

2016 hmmm Did you put R134a into a R1234yf system? Also where is the condenser. If in the rear 40 feet away the efficiency is loss from that distance. If you got cold air while driving, consider yourself lucky.

I'm with you on that, I think Entegra copy lots from Newmar including their confort drive. I think Entegra is calling it E-Z Steer.

I don't count on any gps keeping me out of trouble. Looks for posted signs as you travel and they will give warning of low overpass, trucks not advised at this exit and truck route.

Manuals can be found here;
Ha I meant to post the same link. That's what happens when you post before coffee. Lucky for me they put the Aquahot next to the edge of the bay with the cord reel and electronic for both. easy service except for the diesel filter and antifreeze fluid reservoir is up high. The cable for tv is in there too.

Service don't look hard at all. You can find the manuals here for all models.

I looked up the manual and got some answers.
The Aqua-Hot System is powered by TribridHot™ technology and uses one or a combination of the following sources:
1. The 120 Volt-AC Electric Element: When plugged into shore power, the electric element lets you use the power you are already paying for to provide heat and meet your light duty hot water needs.
2. The Diesel Burner: This is the Aqua-Hot’s most powerful heat source and provides all of heating and hot water needs in cold temperatures or dry camping.
3. The Vehicle’s Engine: When driving or idling, the engines surplus heat is transferred to the Aqua-Hot providing interior heat and limited hot water without burning any other fuel.
Tempering Valve
The Tempering Valve for the Aqua-Hot mixes the heated domestic water from the boiler tank with cold domestic water at the present ratio to reduce the risk of scalding. This valve is located in the back of the Aqua-Hot unit. Reference page 7 (part #19). To locate the Tempering Valve, remove the access cover page 7 (part #4) and then the thermostat access cover located above the burner. Reference page 7 (part # 19). The pink paint witness mark verifies that the Aqua-Hot is set at the correct factory setting and did not get tampered with during shipping or installation. Verify that the Tempering Valve is set at the proper temperature by using a digital thermometer at one of the hot water faucets. The water temperature should range between 115°F to 123°F. If the correct temperature cannot be set, please contact Aqua-Hot Heating Systems Technical Support Department at 1-800-685-4298 for additional assistance or visit our web site at www.aquahot.com

- Normal driving will heat the coach water, none of the AH items need to be turned on. Driving will also provide coach heat by just activating the coach thermostat and call for heat.
- Most of us have AH 450 or 400 models. If the coach heat is running, and hot water is turned on, the coach heat will stop until the demand for hot water has stopped. These two AHs have single heating elements. The AH 650, has two elements and you can have both coach heat and hot water at the same time.
- Wayne, $350 seems a bit high. Lloyd DeGerald, one of the AH gurus, goes to our AC rallies and does the full service, with parts, for $200.
I checked like I said I would and found I can set the temperature with the Aquahot on without electric or diesel and it should work for both hot water and heat while driving. If I don't need the heat on should I still have hot water?

Let me be sure I got this right. While the engine is running and you are driving the coolant circulates through the Aquahot and give you heat and hot water. All I have to do is turn on the thermostat if I want heat. I have to check those setting tomorrow.

Don't forget water pressure. Always use a pressure regulator to keep water pressure below 40 psi.
