Yup, replaced all of mine with parts from Prevost about 6 years ago. Big quality of life improvement.

Here is one of my “eBay” valves, assembled and disassembled. The 24vdc rating only applies to the coil (the black part). I’ve taken a 24vdc coil from one and put it on the valve of another (that maybe had a 12vdc coil originally) to better match the port configuration and orifice sizes. It’s just a jamb nut on the top that holds them…

I also think you could probably just use a Norgren valve from a later model coach in its place. It might be easier to just fabricate a new mounting bracket than to hunt for the right Skinner valve. Yours is probably plumbed with copper lines like mine, so that adds a bit to the challenge of swapping for a different style.

I buy them on eBay. Remember that you can usually swap the solenoid from one to another, although I have found some that have slightly different diameters that won’t work. Not sure how to tell that up front, so it’s a bit of a gamble.<div>

You might have to take some photos of your steering compartment for us. Maybe Liberty converted your 1984 different than mine?

Mine are on the ceiling of the steering compartment, directly under the driver seat. Those Skinner valves are a couple of hundred dollars each new, so I buy them on eBay when I can. You can swap the solenoid, but I try to keep the orifice the same.

I’m guessing you have the six-pack of solenoids in the steer compartment like I do. Looks more complicated than the modern setups, but mine works fine. I’m no air system expert but let me know if I can check anything on my end for you. Liberty made modifications to the suspension, but my bus didn’t come with Liberty manuals.

As for the…

Can’t do it with a full-height unit in my bus, Bill. It will hit the ceiling no matter how you tip it up from horizontal. I don’t know when the XL went to higher ceilings, but mine are about 75″ at the peak right now without a finished floor or ceiling. These two units together are a little wide, but it’s worth it to me to gain the space.

Might as well provide some updates. Two of my biggest challenges were:

1. Finding a shower base that was big enough and had a good drain placement. That was a big headache because I really needed a corner drain to make it work with my layout (i.e. not hitting something with the hole in the floor). None of the single threshold bases (alcove)…

It’s still open right now. I will probably use spray foam, but am concerned about maybe needing to remove the fiberglass panels that replaced the upper windshields at some point in the future. I figure that would destroy the insulation and make it difficult to replace. I’ll probably cover the area with thin plastic and areas of weak…

I pivoted to another project about 18 months ago, but am finally done with that. I also just recently sold the boat I had in charter. 2026 has been declared the year of the bus around here. Finally settled on my layout and am working on plumbing now, then electrical. Can’t really call mine a Liberty Coach any more, except for the…

I went out and took a picture of my filter installed. Sorry for the rat’s nest of wires. Projects!

Richard, I replaced the one in my steer compartment with Part #: 641338 from Prevost a few years ago. It wasn’t a tough job. I have another one for the filter in the engine compartment, but I haven’t gotten around to that yet because it looks a little more complicated. Maybe I’ll take another look at that one since I have some stuff apart…

Thanks for adding that feature. Incidentally, if people would add a basic signature, it would really highlight the issue with older replies to posts being attributed to the wrong user. That’s still widespread.

I’ve spent more time shopping mini splits than I care to admit. I picked up a 12k Mr. Cool heat pump a few years ago to use on the bus, but eventually installed that in my shop after I decided to gut the bus. Good thing, because I failed to notice that it was 240v. It works great though. I have an 18k AirCon heat pump mini split…

I considered using a ducted unit in my bus since I freed up an entire bay by deleting the OTR HVAC. I couldn’t find any that were 120v, only 240v. I thought that might limit me in some power situations, although I haven’t really settled on my electrical design. The 240v outdoor units were also too tall for my bays. I’d love to avoid…

While we’re in the engine compartment, I also completely rebuilt the rear electrical panel. Not sure if I posted about that before. I’m also not sure if I did a good job, because I haven’t tried starting the engine since last summer. Sure looks nice though! I’ll have to find better before and after photos for this job, but I…

I also replaced the plywood covering the top of the engine compartment. It had a lot of rot, I suppose due to years of the Cruisair evaporator freezing and then melting everywhere. No other signs of water penetration back there. I replaced the fiberglass insulation and what I guess is meant as a vapor barrier, using foam board and a nice,…

I don’t have any drawings to post yet, but am at a point where I need to decide. It really is a game of inches. My main goals at this point:

1. change from side aisle to center aisle

2. make moving around the bed less of a squeeze

3. make the bathroom less cramped

4. incorporate a larger refrigerator

Everything else is really just…
