Sorry, this is off this subject...when you have a chance, could you measure and post the inside dimensions of the pantry drawers on your 3341. Trying to plan for some modular containers to fit in the drawers.

PS: Once I take delivery, you will have company as a Complete Air Head.

Excuse me Gil but no hijacking posts here and it is AIRE HEAD not air head.

Thank you very much.:fl owers:

Quincy...

At the expense of continuing this inappropriate hijack, I will merely say that to qualify as a "Complete" Air Head you need to misspell AIRE HEAD.

These new coach systems need redundancy to cover storage situations. As designed the high end Newmar coaches cannot be stored without shore power unless you allow unattended generator autostart. I really don't like that idea.

These coaches need enough solar coverage and associated chassis battery support to be indefinitely stored outside.

This is a fantastic read. I have a hard time believing that an engineer could not design a proper storage solution for a high end coach. It will be interesting to see what the 19’ models for Newmar has but one would expect that My Rozie and the Silverleaf system will make it’s way into other coaches. Newmar must realize that not every owner wants or has the ability to plug a coach in while stored. Try bringing your coach in for service and finding a dealer that can keep all coaches plugged in at all times.

I never see the lightning bolt when the house batteries are being charged by the solar cells, even when the solar controller goes into float. So I think SilverLeaf is watching the Xantrex charger. When it sees the charger go into float it closes the bridge between the house and chassis battery charging both.

There is no interface available in Newmar implementations of SilverLeaf to allow a connection between the solar charge controller and the TM102, so SilverLeaf does not know the solar charger is floating, thus it never opens the bridge to the chassis battery.

As to the RFID FOB, it is my understanding once the FOB is within 3 feet of the ignition circuit, it "wakes up several" circuits from the chassis battery taking more load from the chassis battery.

Much of this is guess and speculation by watching things work. Very little documentation on all of this.

Any time I leave the coach unplugged in the sunlight, I use a wedge to keep the switch for the battery link down, thus opening the chassis battery charge bridge to allow the big solar cells to keep both sets of batteries topped off.

Not sure this is 100% correct, but from I've seen, when the chassis battery reaches a certain level of charge (I'm guessing around 12.8 or so) the charger then bridges over (yellow lighting bolt) and charges both batteries together.

I have and I do! NIRVC with locations in the Atlanta, Dallas and Phoenix and a soon to open location in Las Vegas has and used a 50 amp plug in for everyparking spiny on the lot, including inside whether being in Service or parked in their300 space buildings. If it’s not moving, it’s plugged in. I know, that’s just one dealer but it is one of the many reasons we buy and service with them. JMHO

I’ve heard great things about National Indoor RV. That’s encouraging, my hope is to have dealers up their service game knowing RV’s are currently flying off of dealer lots. Most service facilities I’ve been to will only supply power for the day you’re in service, FL Gaffney being the exception.

I’m wondering if the two different battery types is the reason Newmar engineered the solar charge system to ignore the Chasis batteries. Lead acid and AGM have different float voltages...?

Don't think so. Any modern solar charge controller is going to use the same schedules for charging AGM batteries as the Xantrex charger.

This is a logic issue in the TM102 controller. It is programmed to open the bridge after an appropriate delay when the Xantrex is charging the house battery or the chassis alternator is charging the chassis battery but does not sense solar charging.

I talked to SilverLeaf about this issue last fall when I installed my solar panels on the NA. SilverLeaf said they have the logic to open the bridge for solar charging but it is not part of the Newmar package. They told me the same SilverLeaf equipment in coaches made by other manufacturers do have the logic to open the bridge when the solar controller is charging the house batteries. Told me to talk to Newmar if I wanted it. That went no where as you might expect.
