After an 8 year wait, we finally were able to move from a 25' covered slot, to a 28' covered slot at our storage location! As a result, we are considering swapping our 2014 2350 to a 2552.
The rear of our 2350 (E350 chassis) sagged significantly when loaded so we installed rear air bags. That has worked great, not only eliminating sag, but improving the ride. We tow a Wrangler and our towbar setup is based on the back end of the 2350 not sagging.
After watching a video regarding Liquid Springs, it appears that you can adjust height of the coach above the rear axle, but it resets to normal height when driving above 15mph. I understand that Liquid Springs adjust to keep the ride smooth, but do they also prevent rear overhang sag and accommodate for a loaded out coach? In other words, is "Normal" ride height the same, regardless of load?
Thanks,
Bob

I would contact Liquid Springs with that question.

Thanks Ron, and I plan on doing that - just looking for some feedback from owners that have experience with the system and how it works for them, with regards to sag.

The Liquid Spring system uses ride height sensors to position the height of the coach, so the coach height remains the same independent of load.

Perfect - thanks! 2o2

BOBKBUSCH, We own a 2020 2552 equipped with Liquid Springs. I have always used the normal setting while driving. I have used the high setting when going through an upgrade at a gas station so the rear end wouldn't hit. I have also used the low setting to level out a hard to level campsite. In the low setting, the jacks don't have enough room to extend. Liquid Springs also aids to stabilize the load side to side & rear to front. I also tow a Jeep Wrangler Unlimited. In the normal setting the tow bars are level. I haven't driven a PC without Liquid Springs, so can't talk about any difference in handling or ride. Also, always turn off LS if raising or lowering the jacks. There is a communication problem between the jacks & LS. When LS is own, the system is sending a signal that interferes with the jacks. Hope this helps, Chuck :)

Yes, thank you for the info! I have a custom tow bracket on my JK Wrangler Unlimited. I had the tow pin receptacles cut off my Blue Ox baseplate and mounted them to the front of the frame, behind my front bumper caps. This way, not only does it completely hide the towing hardware when not in use, I also did not lose any ground clearance/approach angle that would have been lost if I mounted the baseplate under the bumper.
Since my tow pins are up on the Jeep's bumper, I use a 10" riser from my 2350 receiver. Any sag on the 2350 back end results in an unlevel tow bar. With the airbags, I've eliminated that issue - and improved my ride. I was hoping the Liquid Spring system would operate similarly, with regard to sag, and it sounds like it does.

To everyone here who has the $ 5 digit Liquid Spring option, would you say it was worth the extra cost? How reliable has the system been for you thus far? Is the system heavier than the stock springs, hence reducing what you can carry? I am simply curious.
Somewhere I recall reading people were test driving the same model motorhome with and without Liquid Springs for a direct comparison. That would make a great Youtube video.
A lower cost non-adjustable simplistic alternative to Liquid Springs are Sulastic Shackles, but I never read anywhere of someone who has them on their motorhome, PC or otherwise. CLICK HERE (https://www.youtube.com/watch?v=sNqTNsQwWd4) to watch a video on a comparison. They offer one specifically for the E350 and E450 motorhome chassis. They run roughly $400/pair.

At the risk of hijacking this thread. Those of you who have Liquid Springs, what is your maintenance regime? We got a quart bottle of liquid that says Liquid Springs. Then the pamphlet we received says to be serviced by authorized tech only. How often do you do what? Our rig is about a year old so we want to keep things right. Can you go to a local shop or back to the mother ship?

Ron, as stated, I can't speak about the ride difference for a PC. I can however share that the ride & handling on a 36' class a was much improved. We bought our PC used & much of the literature packet was missing, including the liquid springs literature. But from what I have been able to gather, the addition of liquid springs added about 480lbs. The sticker on the passenger door frame (OCC) states that we can add 1,880lbs. Which has proven to be enough for us. We carry very little water & the tanks are mostly empty. I have ordered a print copy of the owners manual from LS. Maybe another PC owner (GARMP) can better answer the weight number. GARMP, as far as I understand, the only maintenance that a owner should do is make sure all bolts are torqued to specification. Any other input concerning LS is much welcome. :) Chuck

After our first 3000 miles we made an appointment and took our PC2351 to the Liquid Springs factory in Lafayette Indiana (just a 3 hour drive for us). They checked all the torques and made sure everything was good. I don't know if it is typical, but they were done in about 1 hour and did not charge us for the service. We even received a factory tour, they have a very impressive modern facility.

We had a used 2017 2910D for 6 months (no LS) in 2019 and then traded it to the factory for an almost-new 2019 3100 with LS. The 2017 rode pretty well from purchase place in Fort Worth up through windswept Texas, Oklahoma and Kansas, especially compared to what our previous 42 ft diesel pusher would have done. We liked it.
We then traded to the 2019 with the LS and really like the capabilities. Raising the back to get in and out of a sloped driveway; adjusting ride quality based on road conditions (Comfy, Normal, Sporty for wind) has been a help. Never had a sag problem so cannot comment. Have also not had any load/ride issues even with the added 400+ pounds for the LS.
Took the PC to LS factory in Lafayette because we had no record of the safety check specified at ?2500? miles. Great folks - in and out in an hour, no charge and we even got some free t-shirts and high-end coffee mugs!
Would we pay the cost of LS on a new rig (upwards of $10K)? Not sure. But we certainly like it now.
One point - LS only raises and lowers the rear axle. Not as bad as it sounds because the horizontal arm is very long and, because of where it is attached in front, you can actually raise and lower the entry step with it due to the geometry which is a great feature. LS has rolled a multi axle option but only for the Ford F53 chassis so far.
