So, a summary for anybody searching for this thread on removing HWH Slide-out Rail hydraulic cylinders:
This is a 2003 Monaco Dynasty 42' triple-slide (Regal).
I was unable to remove my Road-Side hydraulic cylinders because they hit the bottom skirt of the Curb-Side slideout. I jacked up the Curb-side (kitchen) slideout, but was unable to get enough height for the cylinder to clear below the slide-out. So I wound up cutting a notch in bottom aluminum skirt of the curb-side slideout as pictured.
Initially I thought I would need to disconnect the rail arm from the slideout to get enough height. I tried that on the rear end of the slide and the slide hit the top of the wall opening well before the cylinder would clear without cutting.
So, when I jacked up the front, I only removed the lower nut from the slide-arm vertical adjuster. This allows the adjusting block to raise up within the arm and gave me enough height to pass through the notch without having to remove the bracket from the slide-out.
Serarch terms: HWH Hydraulic Cylinder AP25201 AP15344 jack up lift raise slide clearance remove

Hi Wamcneil; Great write up with pictures and how and what you needed to do to get the cylinders out. Sorry you had to notch the slides, but by the time you are done, you will be the only one to notice the repair. I have the same problem with jobs like yours and the wife always says, you are the only one to notice the repair. I reread your post and have a question and I know you have been very busy with this project. My 01 Windsor just has a kitchen slide and it is electric. In case I missed the information in your post, what was the reason for the repair? Were the cylinders leaking or not extending and retracting properly? Also, are you having the cylinders repaired by your self or replacing with new from HWH. Like you, as a person who tries to do most of the work themselves, I am just curious. Thanks in advance and what a job!

Thanks for the encouragement 8.3.
Yes, 2 of my cylinders were leaking. It got to the point that air got in the cylinders and the slides racked sideways and started to cause damage.
I'm planning to take the cylinders to a hydraulic place and have them rebuilt. Hoping that it's straightforward to overhaul them and there's nothing going on to force their replacement. I consulted HWH tech support before starting this and he didn't push me toward buying new cylinders.
HWH tech support was very helpful and responsive BTW.
