How should I store Class B RV?

[Jjrho]

Hi, 2017 era 70...class B sprinter.... I don't use my rv much..it's under a shaded structure with tires covered....I start it up every 2 to 3 weeks n run the gen for 15 min...LPG onan.... I have a trickle charger on the chassis battery only and the E system for coach is shut off.... the coach battery seems to be still charging via solar.... should I plug in shore power 15A ? If so, do i need to turn the coach power button ON ?

What's the best way to keep rv on standby ?
Btw, I do move it about 2 to 3 ft in opposite directions too every month for tires....

Tnx for replies

Sounds like you already have a good plan.

Small points to consider?
The battery disconnects can be misleading when we store! They do cut off a lot of the load but they also leave some that kill the batteries over a couple months or so.
To avoid any chance of hazards, the safety items are left on!
One way to verify this is to look at the green indicator light that many propane or CO detectors have. Turn the disconnect and see if that light is still on?

When storing with solar and a trickle charger, I favor just adding a strap between the positive coach and chassis batteries. They are connected by the solenoid/BIM system while we drive and I like to get the same connection does when stored.
That lets on existing system keep both charged.

But this also has some small downsides if we fail to remember to disconnect that strap when we start using the RV. It IS possible to run both down when camping if we leave them connected!
But if you are a type which checks things a bit when pulling it out of storage or even monthly, we are likely to check the battery water and a strap across them is not easy to miss taking off!

If both sets are reasonably well charged when storing, this strap doesn't have to be very big as the current flow from one charged battery to the other charged battery is very small. I made a strap of #12 as that is plenty big and handy around me.

On plugging into power? The converter is often disconnected from the batteries when the disconnect is turned off, so plugging in with it off is not going to charge the batteries!
Two options are easy for me.
Plug in the trickle and let the strap do both while disconnect is off Or plug the RV cord and leave the disconnect on to charge the coach and add the strap to carry it over to the chassis.
One big thing to potentially run the chassis side down is the step as it stays hot on many RV. If it is left out, it may also have a light burning under it full time to really kill the chassis battery quick if we don't notice that light when in daylight!
