What is an S2RV Chassis?

An S2RV chassis is a type of motorhome chassis manufactured by Freightliner Custom Chassis Corporation (FCCC) and is typically used for high-end luxury “Super C” motorhomes.

Our 2022 Entegra Accolade XL

Some examples of RVs that have an S2RV chassis are:

  1. Tiffin Allegro Bay

  2. Entegra Accolade (and Entegra Accolade XL)

  3. Jayco Seneca (and Jayco Seneca Prestige)

  4. Thor Inception / Thor Pasadena

  5. Renegade Valencia

There may be other RV manufacturers that use S2RV chassis as well, but these are some of the most popular ones.

What Leveling System Comes with an S2RV Chassis?

Our S2RV chassis is equipped with an Equalizer leveling system that can be operated from the dash or with the Equalizer smartphone mobile app.

How We Level our Super C on an S2RV Chassis

We belong to and pay attention to many of the RV internet forums (especially the Facebook groups). We’ve noticed that EVERYONE has their own method of leveling their RV.  We wanted to share how we go about leveling our 2022 Entegra Accolade XL (same as a Jayco Seneca Prestige).  Here are the basis steps:

Step 1:  Find a Relatively Level Spot

See this Amazon product in the original post

The first step is to find a level spot to park our RV.  We use a smartphone app call LevelMatePRO to assist us.  Once the LevelMatePRO mobile app is properly calibrated, it will tell us how many inches each tire (or dually) needs to be moved up or down in order to level the RV in real time.

Usually, I’m outside the coach, trying to eyeball what appears to be the most level spot at our campsite.  Kasie then moves the rig to various spots while looking at the LevelMatePRO mobile app. 

Of course, we don’t have to use a smart phone app to find a level spot at our campsite.  An old-fashioned bubble level or 4-foot level will do the trick, but that takes a LOT more time.  However, we like the ease of having the real time data in the driver’s seat that comes with the LevelMatePRO.

Step 2: Use Leveling Blocks or Boards (if Needed)

Sometimes it is downright impossible to find a relatively level spot.  We may be off as much as 7-8” in some direction.  In such a case, we need to level so that each of our FRONT tires is no more than 4-5” from being level (more on that later).  We carry a few leveling devices with us for that purpose. 

·       If only our rear wheels need raised.  

If only one or both of our rear wheels need raised, we have two 2x8” boards that we can roll our wheels onto.  We like to use these boards if our rear wheels need raised because the boards are long enough that I can place a single board underneath a pair of our rear wheels.  (Note:  I also like having these boards on hand just in case we might get suck somewhere so we could place them underneath the tires.)

·       If only our front wheels need raised.  

If only one or both of our front wheels need raised, we have some Beechlane levelers that are a little easier to roll onto so if we just need the front wheels raised a bit, these are a great option.

·       More complicated leveling. 

We also have 20 stackable Camco leveling blocks that we place under the relevant wheels. We only use them to raise the front wheels because they pretty much get crushed under the weight of the rear wheels.

We also own these Camco Leveling blocks….just in case. The first time we used them on our rear wheels, the weight of our big Super C caused some of the plastic to deform. We don’t recommend them for large rigs, but they might be okay for smaller RVs. We’ve also found that we can use them on the front wheels.

Once we think we’ve found a decently level spot using our LevelMatePRO (and used the boards or leveling blocks as needed), we stop and engage the parking brake.

Step 3:  Ignore the Equalizer Auto-Leveling Function

Our S2RV chassis comes with an Equalizer leveling system that includes an auto-leveling function.   With a push of a button, the RV is supposed to magically level itself.  However, in our experience, the auto-level function tends to “level” the coach with the front wheels much higher than they need to be.  In fact, in many instances, the auto-leveling function will result in the front (or sometimes even the back) tires coming off the ground.

So what do we do?  We ignore the auto-leveling function and level the coach manually. 

RV owners often disagree about whether having the front tires of the ground is acceptable.   The 2022 Entegra Accolade Owner’s Manual (page 40) says: “Never lift the wheels off of the ground when leveling the motor home.” Likewise, the Entegra Equalizer Owner’s Manual (page 4) states: “Do not attempt to lift the vehicle tires off of the ground.”

We are in the “all tires down at all times” camp.  

Our Super C manual states that the tires should never be off the ground!

We level our Super C manually to avoid having the tires come off the ground.

Step 4:   Drop/Extend the Rear Jacks (HHHHiiiiisssss!)

Using the Equalizer mobile app, we drop the rear leveling jacks first.   As this occurs, the rear air bags will start to deflate such that an audible “hissing” sound will persist for several minutes.   Don’t worry.  That’s normal. 

After the hissing subsides, we raise the rear jacks slightly.  As this occurs, the rear of the chassis will lower because the rear air bags are no longer inflated.  We then drop the rear jacks again so that the are properly grounded. 

(2024 Update): We recently added a rear air back dump valves so that the air car be released more quickly to expedite our set-up. Here’s the basic design:

Our rear air bag dump set-up.

Step 5:  Drop/Extend the Front Jacks

After rear air bags have been deflated and the rear jacks are grounded, we then extend the front jacks and ground them as well.

Step 6:  Level, Level, and Level Again

Now, the real leveling fun begins.   We need to raise and/or lower the jacks to make the RV level. 

We’ve found that is it easier to level the coach using two phones.   In one hand, we have the Equalizer leveling app open to control the position of the leveling jacks.  In another hand, we have the LevelMatePRO app open to see precisely how each tire needs to be raised or lowered in real time.   We start by leveling from front to back, and then turn to leveling from side to side. We always make sure that ALL of the tires are on the ground at all times!

After the LevelMatePRO tells us that we are level, we are almost done. 

Step 7:  Double Check Our Work

After the LevelMatePRO tells us that we are level, we double check our work the old fashioned way.   That means getting out the bubble level and/or the 4’ level inside of the coach.  

Double-checking our leveling work with a 4-foot level

Step 8:  Extend the Slides 

The Owner’s Manual to for our Entegra Accolade has conflicting information about whether the coach should be leveled with the slides extended or the slides retracted.  On one page, the manual states:

“The slideout room should be extended (with the air suspension fully aired up) before leveling jacks are deployed. Wheels MUST be straight. When the coach is leveled, air bags are dumped of air which lowers the fenders below the tops of the wheels. If the wheels are not straight, fenders and/or tires WILL be damaged. DO NOT DUMP AIR FROM AIR BAGS UNLESS WHEELS ARE STRAIGHT!”

 Then, on another page, the Owner’s Manual states: “The recreation vehicle must be level before operating the slideour room.”

Level before extending the slides? This page from our 2022 Entegra Accolade Owner’s Manual says “no.”

Level before extending the slides? This page from our 2022 Entegra Accolade Owner’s Manual says “yes.”

We’ve decided that extending the slide when the RV is not level would cause the slide mechanisms to undergo stress.  As such, we level our coach before extending the slides.

Step 9:  Triple Check Our Work (& Level Again?)

Once our slides are extended, we then check to see if we are still level using the LevelMatePRO mobile app.  We like to use the bullseye and 4’ level here as well to double-check our work. 

In our experience, extending the slides does not change how level we are in any material way.   At most, extending the slides results in no more than a ¼” change.   In the unusual case where we need more than a ¼” adjustment, we would use the Equalizer mobile app to manually move the jacks slightly until all sides are level with the slides out. 

Step 10 (optional): Celebrate

After finishing the leveling process, it is time to celebrate. For us, that usually means grabbing a beer while we set up the rest of our campsite and RV. So cheers to you! And good luck leveling your RV!
