Leveling & Slideout Deployment --> Power ?

Hey Gang,

Question for those of you with slideouts and levelers. Some background on why I'm asking: In my soon to be traded Minnie Winnie the manual states rather clearly to keep the engine running when deploying my slides. Both slides are Schwintek. My Winnie does not have levelers, so for me it was a simple matter of driving up onto the blocks, putting it in park and setting the brake, and deploying the slides while the motor was still running.

Fast forward to now, and I have a Schwintek slide in the back, another non-Schwintek slide in the front, and Big Foot levelers.

Do I keep the motor running for all of them so the alternator can supply ample juice? Will the Big Foot levelers hollar at me for having the motor on? Or do I level w/ the motor off, then start it back up to deploy the slides? Or do I do it all off the battery?

I believe my Greyhawk has a single Group 27; which theoretically would be fully charged upon my arrival given the converter keeping it juiced while I was underway.

The simple answer is Yes. This ensures you will have ample juice. Why risk it, over time it will likely cause a problem. If you do it with the motor on all the time, you just reduce risk.

Yes to which part?

If the BigFoots will let me deploy w/ the engine on while in Park and with the parking brake set, I'd just assume do it that way. Keep the engine running, drop the levelers, pop the slides, turn the engine off.

Is that what you meant?

I have 31 FS w/ 2 slides. I park, stop engine, set parking brake. Set levelers. Then slide outs. Coach battery voltage stays above 12 w/ all this.
I reverse order when closing up. Bring in slides, then raise levelers.

I have never tried to lower my Bigfoot levelers with the engine running. I do know if I turn the ignition key when they are lowered, the Bigfoot control unit beeps madly to prevent driving off with them down.

We've never had the engine running for slides or levelers. Maybe we're doing it wrong - rereading the manuals would be less fun than sending Jayco a note to ask their opinion.

Manual states that you first level Rig and have a full charged 12V battery and/or connected to shore power before extending the slide outs......

I would assume that if you're boon docking that you have engine running/generator to ensure enough power to extend/retract slide-outs.

Boondocking or not, I turn off the engine and level. Then slide out. Never felt any reason to do it differently.

Never tried leveling with the engine running, though I would be interested in knowing if the bigfoots would deploy.

On my 2015 31DS, when the engine starts the bigfoot levellers automatically retract if deployed. I have never tried to deploy them with the engine running. After driving a few hours and then stopping somewhere, I have always had lots of power from the battery to deploy the levellers and slides. Cheers.

Bigfoot levelers are also installed on fifth wheels and it does not seem to be an issue as long as you have good batteries.
