I currently have More Ryde on my 2552 order but am considering upgrading to Liquid Springs before its built. Curious to know:
1) Who loves each one and why?
2) Maintenance required for each one?
3) Any reliability comments on either?
Thanks everyone!
One of the features I like about the Liquid Springs is the ability to raise/lower the rear end of the RV. I use this feature every time I back the RV into the driveway to keep the tow bars from dragging on the concrete. On the 2007 RV, I would always have to remove the tow bars from the hitch, otherwise the tow bar would drag when I would go up the incline of the driveway. Now I can leave the tow bars on, I just raise the RV before I back up and it clears with ease. This saves time plus I can just keep the tow bars on the hitch without having to find a place to store it.
I also found that having the ability to raise and lower the rear of the RV, it has lessened my need to use the HWH levelers when I park. Often times I will pull into a site and the LS is enough to get the RV level front to back. When this happens, I don't even spend the time to use the RV levelers.

I'm curious as to how much up/down travel in the rear is available with the LS system? I don't have levelers.
Thanks,

Good question, I was curious about this too so I took a few measurements this morning:
At the bottom of the hitch receiver, the normal drive mode height is 17 inches. That drops to 12 1/4 inches with LS at low and raises to 20 inches on high. I was then curious what the max height would be with my rear levelers using blocks to fill the gap between the bottom of the levelers and the garage floor (w/ front levelers disabled). I was able to raise the rear of the RV an additional 6 1/4 inches to 26 1/4 inches. So the levelers do add to the range, they even lifted the rear duals off the ground by over an inch with my LS shut off. That is good to know as it would be important to choke the wheels because I believe the emergency brakes only go to rear wheels. By the way, it is important to turn the LS off when using the hydraulic levelers.
A measurement I don't have is what the rear hitch height is for a non LS 2351 on a E450 chassis. I believe the LS nominal drive height is likely higher than the traditional Ford springs. I know my previous 2350 on E350 chassis sat a bit low in the back.
Remember height changes would vary depending on wheel base of the PC model. I have a 2351 which is a wheel base at 170 inches. I also took measurements at the rear wheel well if that info would be helpful.
I was curious what this range would look like on a level so I took and attached some photos. The first is with LS low, then LS in normal drive, LS high and the final with maxed out rear levelers. My level probably does not do justice to the additional range the hydraulic leveler provides. I used a 2 foot construction level sitting on the kitchen countertop (which gave the same measurements as the floor). If you are wondering why the level looks more level when LS is low, it is because my garage floor is sloped toward the garage doors to allow any water on the floors to flow out through the garage doors.
I don't think I mentioned this before, but the LS height adjustment does come in handy at the dump station too. Depending on how level the dump station is, I can adjust the LS to help gravity empty the tanks.
I hope this info answers your question. Probably more than you wanted to know.
