Leveling and Slide Procedure

[p024576kos]

Appreciate advice on the 'recommended' procedure for leveling and extending slides , including when to dump air manually, avoiding air bag reinflation, etc - engine off? engine on? ignition turned to aux position?

Here's the procedure we use on our 2021 Tiffin ALLEGRO Red 33aa;

1. Shut engine off
2. Manually dump air
3. Press auto level (annoying loud pinging sound during this process)
4. Start engine
5. Extend 4 slides (one at a time )
6. Shut engine off
7. Connect to shore power, etc.

This is how I do it . . .

Pull up to site

Hit auto level button . . . automatically dumps air and levels coach.

Slides Out

Turn off Engine

I dump the air manually because I normally put pads under my jacks and my coach rolls forward slightly when the air is dumped.

I do it anyway I want

Spartan chassis, the design of the rear suspension does that. I really freaked the first time I saw that.




As to slide-outs, some mfgrs. state slide out before leveling, others state level first then slides out. OP, read your owners manual-again.

Not sure what your Tiffin manual says, but the above method seems counter intuitive. If you dump the air, then restart the engine, doesn't that just refill the air bags ?

Also, if the last thing you do is connect shore power, etc, you're having to work underneath the slides.

On our Newmar, we pull into site, kill motor, make all connections, put out slides while still aired up, then dump air and level. No need for the engine to be running.

Honestly, I think most people over think the whole slide issue. It's mostly common sense. As long as the site is fairly level, and the chassis is not overly stressed, it probably doesn't matter that much. A quick look at the reveal around the slides will tell the story.

Not exactly counter intuitive. Although older, my coach doesn't air up just starting the engine. I can raise it manually or it will automatically raise when the emergency brake is off and transmission in gear.

In our gas coach we:
1) Look at the bubble levels I installed and determine if the jacks will need any blocking. Add any blocking needed.
2) To operate the jacks, the parking brake must be set and the ignition must be on. The engine can be running or not.
3) Level the coach. I often prefer manual leveling because it is faster and I can accept less than perfect to make sure the wheels stay on the ground.
4) I usually connect the power & water before running the slides out. If the tanks need dumping, I connect the sewer hoses. For 1 night stops, I often don't bother unless we intend to use our washing machine.
5) Extend the slides. The engine must be off to operate our slides.

Ok, so this is this week's version of same question...use Search.

Same here...I must select which version of "auto" hydraulic or air...and always high idle for the FWS.

Does your Owner's Manual have a 'recommended' procedure?

Different manufacturers have different recommended procedures. You might be careful following advice from members who own a coach from a different manufacturer. Although they may offer a procedure that's recommended for their coach, your Tiffin could be damaged by following a procedure that's not recommended by Tiffin.

Take care,

CORRECT!


It really doesn't matter what the correct procedure is for SOMEONE ELSE'S COACH.


You need to follow the recommendations for YOUR COACH!

Here's an excerpt from page 74 of the 2021 Tiffin Allegro RED Owner's manual:

This is exactly opposite to the procedure that my manufacturer recommends for my coach.
