The instruction manual on our 1997 Monaco Dynasty with three point levelers is: slides out at full ride height, dump air bags, deploy levelers. When breaking camp it's air up to full ride height, retract levelers, retract slides. Been doing it this way for 17 years with no issues.

So we just brought home our new MH and my perspective has changed a bit. The new one the MBS chassis requires the engine to be running to put the slides out, but requires the engine to be off to put down the jacks. This literally forces me to put the slides out first - something I have never done on any RV I have owned. granted this is a C but wanted to note that the process really is unique to the unit.

An interesting question asked often on this and other forums. My rig is on a Freightliner XC chassis. I always dump my air first as I was told I could damage my airbags leveling aired up, then deploy the slides. Reverse, slides in, jacks up, air up.

That must be something new for Newmar, they were always level first then slides.
I'm thinking maybe the full wall slide has changed things from the old days.
My 2015 Dutch Star instructions says to leave aired up, don't level first, deploy slides. Same as Ro"n"Joe. I believe this instruction is there to protect the full wall slide. Yes it's backward to some but that's why you follow mfg's instructions. I'm 8 years in following Newmars instructions & no issues.
I'm guessing you have the newer "Star Chassis". I was told at factory pickup that the slideouts are setup to work with airbags inflated. Nothing was mentioned about protecting the full wall slide.

I have to agree.
I'm not one to countermand whatever an RV manufacturer says in its literature provided with the RV, but it makes zero sense to me to extend slides if the vehicle is out of level.
It's simple physics - gravity's going to come into play if things aren't level, and the energy required to move slides in/out will obviously not be the same.

Unless it's mechanically impossible - like my new coach.

way2roll,
That is interesting. Is that what the procedure states in the manual, or is that the way the system operates as it's wired?
On my rig, the slides are electrically "locked out" from going out if the engine is running at the slide controller module. I'm assuming this is to make sure they don't extend while travelling down the road. I always liked that safety feature as we usually had a good collection of kiddos buckled into the slide. ![[emoticon]](https://forums.goodsamclub.com/sharedcontent/cfb/images/smile.gif "smile") But the slides WILL retract with the engine running and that's what I usually do because my main slide has to lift and then slide in, and the extra couple of volts on the battery with the engine running allows that slide motor to work with much less strain. At least audibly.
As for the jacks, they will extend or retract with the engine running, BUT there is this ear-piercing alarm that goes off as a warning as soon as any jack is no longer fully raised and the ignition is turned on. It gets my attention, for sure. Again, to give the motors a slightly easier time of it, I often keep the engine running while extending the jacks lifting the rig. Once leveled, I shut off the engine and extend the slides. Extending is less work for the motors because they just slide straight out and then drop down.
When we pack up, I start the engine to bring in the slides, tolerate the "jacks down" alarm for a short while, then raise the jacks.
When the rig was newer, I didn't need to run the engine to do all of that, but after 15 years or so, I noticed a few extra volts for the motors seems to help.
Anyway, I was wondering if on your rig, someone mis-wired the slide controller so it will extend with the engine running instead of the engine being shut off? It just seems a bit odd for them to be able to deploy while trucking down the road.
As to the other posts, it seems like the majority of rigs which say to extend slides first THEN put the jacks down have airbags. So perhaps, that's the difference? Just guessing. My rig doesn't have air bags and the manual states "Level first, then extend the slides.".

I think most of those that want the engine running also say in the guide “or plugged in or generator on”. In the several coaches we have had I never unplugged until the final walk around, slides and jacks up ready to go. Parking the plug-in is first on my walk around before slides or leveling. The only reason for the engine on is to not overload the battery. With the converter still online no engine is needed. As a plus the neighbor is happy

On my 2014 DP with airbags as I posted prior it is advised to drop air from the airbags, deploy leveling jacks With the engine running (will not operate if not) then move the slides out after the engine is shut down, slides will not operate with the engine running, nor for that matter will the awning deploy with the engine running.

My slides will work while the engine is running. While my directions from Newmar doesn't say to; one very experienced and knowledgeable poster suggests (on newer Newmar DPs) to run the engine while using the slide motors because they are connected to the chassis batteries.
All this leads to as per stated previously, each needs to follow the directions for their units.
