Thanks
You sold your body parts when you bought the Class A !!!

As for the house batteries, I replaced my original leaky, tired, hard to maintain fluid batteries with a nice set of AGM, sealed, no maintenance, no leaks from BATTERY +. Yes the AGM.s are expensive but now all my house battery worries and headaches are gone !!! We recently did a couple on booddock nights in Va. I ran my CPAP machine both nights via the onboard inverter via the house batteries. Sure was nice !!!

I will stick with my new Corvette (AGM) that I sold my perfectly fine Cruze (Flooded) to get. I opted to not consider the ZL1 (Lithium) because they do not come standard with Air-conditioning
Hey now... I can't help it if I'm a po' boy!

Yep... and a General Motors EMD 710 series and Duramaxģ 6.6L Turbo-Diesel V8 Engine are VERY similar... well, both run on diesel.

New Batteries

A engineer friend told me something that really helped my battery life. Get two solar chargers and connect to your coach and engine batteries. The battery cells go bad if not used or charged on a regular basis. One plugs into the cig lighter for the engine and the other I just clip to the coach battery. I have them in the cab window to pick up sunlight. They don't have to be in direct sunlight to work. Hope this helps.

When I bought a used ACE it was about a year and a half old. The house batteries lasted maybe 6 months more and then died. I didn't check fluid level and they were nearly empty. I replaced with Duracell deep cycle marine AGM from Sam's Club for about $160 each. They don't have to be checked for fluid so that's one less maintenance issue to deal with. They are now over 2 years old and I am very happy with the purchase. Also an RV mechanic told me that by leaving the battery switch in "use" position FLA batteries are constantly being charged which will eventually boil out the electrolyte. Only turn on a day or 2 before leaving on a tip.

My batteries are being charged as long as sunlight is hitting the roof mounted solar panels... and I always keep the use/store switch (battery disconnect) OFF when sitting "idle" in the back yard. It's intentionally wired that way... by design.

Your RV mechanic is misinformed. The use/store switch disconnects the DRAIN on the batteries, NOT the charging side.

And if your charge converter is functioning properly, your standard FLA battery will do fine
But you need to keep an eye on it

Mine last 3yrs or so
Iím OK with that

The standard 3 or 4 stage lead-acid battery charger will drop the voltage to 13.1 to 13.5 volts depending on the temperature of the batteries or the converter when the battery is completely charged. This is the float stage. This is the same voltage of a trickle battery charger or battery maintainer. At 68 F degrees, it takes 13.2 volts to overcome the internal resistance of a lead acid battery. At this voltage or a couple tenth higher voltage there is not enough heat generated to raise the battery's internal temperature enough to cause out-gassing. Leaving a lead acid battery even slightly discharged for any significant time will shorten its useful life. That is why most seldom driven, antique auto are kept on trickle chargers.

I pulled my batteries out at end of first season, topped them off with distilled water. Went to a truck tire shop and got an old tractor inner tube for free. I cut rubber mats from the tube to put under the house batteries and the chassis battery. Hooked everything back up. Slapped a little Vaseline on the positive terminals and good till end of season 2. Same thing. Still going 30 months later. IMHO the secret to FLA batteries, deep cycle or not, is never letting them discharge completely.
