Slideouts or leveling first?

Newmar's instructions and official position is slideouts first then leveling. When I queried them the answer was basically 1) the engineers want to avoid any twisting/stressing on the frame and slideouts, and 2) this is really important for the full-wall slide and they chose to be consistent for other slides as well.

This is for electric slides, hydraulic might be different.

In my experience (12 years with electric slides only) it seems better to be level before attempting slides. I had one situation (a tire tread separation) in which the slant of the road made it impossible to get a slide back in after putting it out to get to some tools. I had to pull into the center of the road to get level before the slide would come in.

I'm interested in hearing other experiences, not so much opinions if not based on experience.

Thanks!

I'm a newbie to RVing but the dealer where we purchased and my experienced brother in law taught me to level first and then put slides out - which made sense to me because I would think you want the coach level and in the same position, when you open and retract the slide. It doesn't make sense (to me) to open it in one position, change that position, and then retract it in another position.

Level first then slides out is the only way I've ever done it...

Richard is right. It makes sense to check for frame twist by looking at the gaps around the slides before extending. I walk around every time to check before extending. If there is any big difference noticeable, I will correct.

Slideouts or leveling first?

The theory behind Newmarís recommendation to deploy the slides on the suspension is that the suspension is designed to adjust to the surface the coach sits on and is less likely to twist the frame. The jacks do level the coach but depending on the sequence they are deployed, some twisting can occur (remember the jacks are rigid with no give). Either method suggests the slide trim margins are inspected first.

This topic come up all the time, and I still don't know if there is a definitive answer.

Does Newmar's advice to put the slides out, then level, cover all models, all years, and ones without FWS? I don't like putting slides out when on unlevel ground without leveling first. It's the way I've been doing this in all the RV's I've owned for over 30 years.

I can see the twist being a bit less when the coach is supported on its springy suspension but it would depend on how unlevel the spot was that it was parked on. I can also understand why it would be better to level first and then extend.

On this 2nd approach though, I can see twisting occurring if I leveled solely by looking at one indicator, say at the front of the coach. I would think that if it showed level there, that a twist could still develop if the rear jacks were wrongly deployed.

Ours is on a shorter frame so I don't believe much twisting occurs no matter what. It makes sense though, that longer coaches might be more susceptible.

To answer the OP's question, I have always leveled first then deployed. Never a problem in the 15 years we've had our rig. But, that's what my manual states for me to do. I'd go with what your manual says!

Personally I extend and then level, I have a full wall slide and it is heavy, if I level then extend the weight throw the level off.

And this might be the answer for FWS...

Hi,
Either method works. The rule you do not want to break is one must retract the slides the same way one extended them.

The answer is... what ever method does not twist the frame. If one of your tires is in a deep rut and this appears to twist the frame then either level and check slide reveals or move coach.

Newmar states to extend then level. My dealer stated to extend and then level. I have documentation to the fact from both. Am going to follow these instructions. If something goes wrong it won't be because I did it my way - much too new at this to start improvising.

Hi htmac007,
There are fallacies with both methods if followed without completing the rest of the process.
1. Park
2. Ensure the coach is relatively level (if not, move or level with jacks). Extend before leveling is promoted by Newmar because the coach is on air bags on a level concrete floor when the slides are installed. In the real world this is not always the case.
3. Check the reveal on all slides
4. Extend then level or level then extend, whatever you are comfortable with for the situation.
5. Reverse the process previously chosen to retract

Do not mean to start one of those threads where there is post after post of the same thing. But, one must consider more than the extend/retract step.

I had the same question when I picked up my coach at Northtrail in Ft. Myers.

One service guy told me to extend, then level. The senior service guy explained further that coaches with FWS should level before extending. I even showed him the manual where it says to level first. To answer the OP, I have had trouble with my front passenger side slide. I had to assist it by lifting and pushing on it while the DW operated the switch. I also had to remove and re-insert the jumper on the controller to get it to move.

I always level, then extend.

The FWS scares me every time I operate it!!!

I cringe too every time I have to extend the slides. My FW Slide is chewing up floor protectors like they are for free. Going to Napanee in October for them to check the rollers plus other stuff.
