The house battery switch leaves the CO and gas detector on. Most also don't disconnect the inverter/charger. They are wired directly to the batteries.

He did recommend wiping with a dry cloth prior to retracting if extended for a long period of time, and if necessary remove sticky stuff by using soap and water and then a dry cloth. For lubrication they recommend a dry lubricant like CRC Dry PTFE spray, which is not sticky and won't attract dust.

Having been raised using WD-40 I would myself, if necessary, use it for removing rust (should it occur) or general cleaning of a jack rod, but then I'd wipe it down with a dry cloth given my discussion with Power Gear.

HWH, with whom I also just talked a few minutes ago, says WD-40 is okay for cleaning, but after cleaning the rod should be wiped with a dry cloth, and that no lubrication of any kind is required. They did not issue any warnings about avoiding WD-40, and they in fact recommend using it for cleaning if necessary, but not for lubrication.
If Power Gear I would absolutely follow their recommendations...
If HWH - they have great info on line and very helpful _ AZPete here in iRV2 as a resident contributor

From HWH FAQ's ...

49. Is there something I can lubricate my jacks with to make them retract faster? How long should it take to completely retract my jacks?
Lubricating a jack rod can help with retraction time but if lubrication is necessary, there is most likely a problem with the springs or the jack itself. The only thing HWH recommends to use is WD-40. Refer to the following link for jack maintenance information: ml47149.pdf. The following link gives detailed information about allowable jack retraction times: mi9553.pdf
From above link - If the jack rod has been greased or silicone sprays have been used on the jack rod, use WD-40 to loosen the grease or silicone and wipe the rod clean.

Can I store my coach with my jacks extended?

Yes, this will not hurt the system

55. How long can I leave my coach parked with the jacks extended?
As long as you want. We recommend operating the system occasionally if possible.

56. Do I need to do any maintenance on the jacks or slide-outs while the vehicle is parked with the jacks and slide-outs extended?
There is no necessary maintenance for the jacks or slide-outs while the vehicle is parked. If desired, WD-40ģ can be used on the jack rods right before storing the jacks if dirt has collected on the rods. Refer to the following link for jack maintenance information ml47149.pdf.

57. If Iím parked for a month or two, should I occasionally operate my system?
Yes, it is good to operate the system occasionally but it is not required.

Bottom line - use what ever you are comfortable with... I will follow manufacturers recommendations where ever I can.

I agree...and me too for the most part.

And I meant no disrespect...if it was taken otherwise then I apologize. My intent was to inform, since both Power Gear and HWH were mentioned in this thread. We know people tend to hear the answer they want instead of the answer they need, so I called both and my post stated what each told me.

Both Power Gear and HWH agree that WD-40 is primarily used to clean, not to lubricate, and both agree that lubrication is not necessary. HWH goes further to say that WD-40 is not harmful to their system, and can be used as often as the user wants; Power Gear says never (on my recent call at least) to use WD-40. HWH mentions in their maintenance guide to wipe dry after using WD-40. From the first page of the HWH bulletin: “If the jack is extended, use soap and water or WD-40 on the jack rod then wipe the rod dry with a clean cloth.“

I intend to use WD-40 if needed to clean (including jacks if necessary to remove some foreign matter soap and water won’t remove), but never to lubricate. I have Power Gear jacks by the way.

I still like the idea for when we are parked in our permanent full time spot. If/when I do this I'll use jack stands adjusted to, or wood blocks built to, the exact height I need, but under the frame instead of under the jacks.
Make sure you are on a level surface so you don't induce a twist in the frame. Extending the jacks prevents frame twist.

Our spot in Florida is a flat concrete pad. It was more of a thought experient...I’ll likely stick with what’s been proven to work. Sometimes we engineers “improve” things that don’t need improving.

Of course you can't trust a NON mechanical support mechanism over time, seals can rupture, fluids and air can leak.

You can only trust solidly mechanical - such as a block of wood or pinned jack stands (heavy enough to hold your MH).

This is a same when you want to go under your rig - you're taking a risk when you slide under thinking your air bags or levelers are going to keep you safe.

No problem. I think we are in agreement. My point was also thst thete are different recommendations and best to heed mfg advice.
I have seen a HWH recommendation where there is a slow retract issue to clean w WD-40, wipe then spray "liberally" w WD-40 and retract. They caution that if the condition persists that it is an indication of a problem that should be addressed. The above can / does help and has gotten me thru several mos of use before taking the time to rebuild / replace a slow retracting cylinder.
