Please Help Settle Jacks Argument

We have a placard on our Thor ACE that states: "Unit must be level with Jacks in the down position before operating slides".
I say that means we should always have the jacks down prior to leveling, whether in a level spot or not.
My DP says we only need the Jacks down if we are not level on the site. She also says the slides make the RV unlevel when it is level before we set out the slides.
I've read that you might need to adjust the jacks to relevel after the slides are positioned.
Who is correct?

Well...it depends...which is my way of saying in discussions like this we should all try to find 'some right' in the other person's point of view.

Most RV leveling instructions say to use the jacks to level the coach before putting the slides out - and have the jacks still extended when retracting the slides. Yes - on a very level spot - and if the RV is also level - you could extend the slides without the jacks extended. I hazard to say that I always use my jacks to level on every spot - my full-length-slide can cause a little lean.

Let's hope some others chime in with their experiences ... there's more than one way to accomplish a lot of things with these RVs ... safe travels ...

My husband almost always levels first and then extends the slides. One exception....Penn State Tailgating. If you don't get your slides and awning out immediately after being parked you might never get them out!

FWIW, as part of my research into a jack problem I had asked a tech at Winnebago if we could push out the slide without having the jacks down. He said the coach was designed to allow for the slide(s) to be pushed out without the jacks being lowered, but walking around inside would of course cause the coach to rock some regardless. Since we have a single large slide I personally like the jacks set and the coach level before extending the slide.

The instructions for our 2000 and 2002 DSDP's were to level first using the jacks, then deploy slides. Our present rig won't let the slides move unless it's level using the air leveling.
So, for us, it's always been level first, then deploy slides.

Just my two cents (FWIW) after reading numerous posts over the last year or so on this topic.

My understanding (could be wrong) is that the newer MHs with the full wall slide (FWS) generally say slide out and then level.

Most of us with the older 1/2/3 slides, the instructions say level first and then slides out.

So it seems there is a lot of confusion because we are not always talking about the same apples or the same oranges - manufacturer, model, year of MH, number of slides, size of slide etc all seem to have impacted the manufacturers recommendations.

Bottom line, look in your owners manual or call the manufacturer if possible.

Me, I level then put the slides out.

Hi Ho: I hardly ever bother with the jacks if the coach is reasonably level. The residential refrigerator doesn't care and we don't really notice. We have been doing this for a couple of years now and it doesn't seem to have an effect on the slides.

If we were quite a bit off level, we would use the jacks first, but problems with the Level Legs seems to be a lot more likely than problems with the slides.

For me its always been levelers down then slides out. My last coach wouldn't allow me to operate my FWS unless level. Last coach and my present one have refrigerators in them so that a lot of weight to move if not level

"Lv2Roam2"......gives the best answer.....it depends. Not all coaches are the same. Some don't care about movement (rocking) inside the coach. Monaco DP's had a strict policy of slides out first and then level. Their reasoning.....when the coach was aired up, the chassis was more likely to be sitting level (square) even on unlevel ground. They wanted their slide to be pushed out through "square" openings, rather than openings that were tweaked by pushing the frame in different directions.

Many argued this was wrong for years, even though they didn't engineer the Roadmaster chassis or own one. Now, you're hearing, on many full wall slide models like mine, that they now want the slide out before the jacks go down and tweak the chassis.

The best answer here....common sense. Do you want to deploy slides while parked on a hill or the left front tire in a 10" hole, no, level first? And if you're sitting on perfectly level ground, does it really matter.....no!

With all that said, some coaches, when the slide and even the awning are deployed, can cause the coach to lean to one side. Again, commons sense says use your jacks.

I level first and the deploy the slides.

I have been sitting in a parking area and checked the leveling system. It said the coach was level. Then I started the leveling process. Generally I level manually. I find that on occasion after the system dumps the air the coach is no longer level. Obviously the ride height is doing its job and keeping the coach level when not on level ground.

Auto level the level, then slide the slides.
