2023 Winnebago Vista NPF Chasis Battery Changeout

[Draco1323]

I need to change out the chasis battery on my 2023 Winnebago Vista NPF.

The battery is visable on the lower passenger side when you open the hood, but there seems to be no way to reach the battery terminals, and there is no clear path to remove the old battery.

HOW do I access the battery?

In your Owner's Manual on page 7-13:

it states that on some models, it is located beneath the entry steps, but it looks like that is not the case with the NPF. After looking at this Facebook post:

How do you access the chassis engine battery under the hood/engine compartment for a 2025 29Vista NP. Passenger side. Looks pretty tight.

I am guessing that somehow you drop the battery out the bottom or will have to disassemble some things that are over the battery.
Do you have some exceptionally large Lithium battery taking-up all of the regular under-the-step battery storage space?

Yes. Lithium storage batteries for the coach are under the entry steps. The chassis battery is on the passenger side, just beyond arms reach when you open the hood.

Open to some thoughts about WHY change the battery?
One of the big things I know about the newer batteries is that it is easy to think they are a problem when it is actually some smaller part like connections that make it look like a bad battery.
Since it seems near impossible to reach, would there be good value in testing other things that are so common on making it seem like a bad battery?
I'm assuming this is not an older style lead acid?
Not meant to say you are wrong because we don't know what you've done. But it could save you a bunch of trouble if it was some smaller part that would still be a problem after a battery change!
Not a case of the newer RV not being driven often enough to keep parasitic drains from leaving it act like a bad battery? Something I ran into with a car not driven much during the main Covid issue! Newer cars have far more drains to run them down quicker than I expected!

Drop the battery out the bottom or remove the grille. I had to do the latter with my Class A.

Yes, the area under the steps is for the coach batteries.

Surprisingly, I asked thr RV dealership how to change out the battery and they did not know.

Actually there is nothing wrong with the battery right now. I have to assume that it is getting close to 4 years old and thar is about the useful service life for a battery in Florida. I am just looking ahead to when I will eventually need to change it out.

I also need a way to reach the battery terminals so I can use things like a portable air compressor.
