Default Advanced RV's Self-Leveling

Advanced RV works with a Dutch company to install self-leveling on its Class Bs at the touch of a switch. It levels front to back, side to side or both and automatically seeks the lowest needed level. It also works with their VB Air-suspension installation. They will retrofit, so I will have to see this at Advanced Fest May 4. I rarely need leveling but this video is compelling.

The base price in UK is about $6.5K plus installation so it could be a $10K option. Not mentioned advantages are wheel changing and security. To protect the van from being stolen just lift wheels of the ground and block the controller.

Wow! I've had experience with hydraulic levelers on a 23 foot coach. Until I used them I thought they were useless but after making use of them I was at a loss how I was able to do without them. They were invaluable for sleeping in spots that would otherwise have been unusable.

Mercedes has an unbending rule about drilling into their chassis, so everything has to be clamped. Interestingly, HWH markets a clamping hydraulic leveling system designed for the Sprinter but while Mercedes doesn't prohibit it's use under warranty, for some reason they don't approve it. I wanted to retrofit them on our 210 but HWH said there was insufficient clearance to ground to employ their design.

I notice that they use the vertical plunge setup rather than the kick down setup with a return spring. One advantage of the latter is on days when you OD on stupid pills and drive off with your levelers down, the kick down levels will retract sufficiently to avoid damage whereas vertical plunge levelers would be trashed. Don't ask me how I know.

That looks like a sweet system. Drilling no holes and using clamp mechanism to the frame part is the same way I mounted four 6V AGM batteries behind the rear wheels under my Sprinter.

Just having a stable van is useful even if you don't need much leveling. Video does not mention Mercedes view on these levelers. Video does mention that the hand brake must be set for system to engage. That might mean they would retract if you release the hand brake and try to drive off. Also found this note in operating Manual from E&P:
"REMARK: Depending on how the system is connected, all jacks are retracting also when the parkbrake is released or the ignition is switched on."

That could be kind of weird if they retracted every time the autostart kicked in to charge the batteries.

Reading the manual further this comment on page 27:
"Jacks are extended and you accidentally drive off: the system will immediately give an alarm and the jacks are automatically retracted as soon as the hand brake is disengaged. In case of vehicles with a pneumatic brake installation, this takes place when the engine is started."

When an Advanced RV auto starts you cannot put it in gear to drive or step on the foot brake or release the handbrake. It will turn the engine off immediately. I don't know, but I suspect it could auto start without retracting the levelers. Even though auto starting would be a rarity as I have mentioned many times, you can program and turn it off at the Silverleaf screen if in fact it would conflict. Also with a little common sense with all the information at hand about your battery status you should be able to know if auto start in the middle of the night is remotely possible. i.e. I think you would have to be extremely stupid for this to be a concern. I will probably learn more at ARV this coming week if any of my suppositions are wrong.

BTW, there is about a two inch up or down auto or handheld control manual button forced leveling with the VB Air Suspension which many times eliminates the need for those lego leveling blocks but it does nothing for any side to side leveling. I'm intrigued by the system but seldom ever need leveling blocks. Many campground sites seem to have a natural slope back to front down toward the drive road for drainage. VB Air Suspense takes care of those situations most of the time.

Is this a real triple axle Fiat Ducato on E&P Hydraulics homepage? Or just an artist's overactive imagination?

apparently it is real.

Probably handles like that 1970s GMC MH; it was front wheel drive as well. The traction sucks.
