I'd suggest you just unplug (not just turn off) the refrigerator for several hours at a time periodically. You will see the correlation quickly if that's the source.

The first time I noticed it was in ABQ, NM at an RV Park. The water pump was off the entire time.Has anyone mentioned the water pump?
I don't have the guts to ask . . .What if I get an answer?I still posit a simple “Who’s there” will solve this.
I think I have only heard it with slides out and steps out. I have yet to put the awning out.Does it happen - slides in/out? Awning in/out? Steps in/out? Just a few of the systems that have movement and could possibly cause strange noises.
Does it only occur when the jacks are extended? Some hydraulic jacks make a pretty loud "pop" sound now and then when they settle some after being deployed. Sometimes the popping depends on how far the jacks are extended.I think I have only heard it with slides out and steps out. I have yet to put the awning out.
BTW, I heard it again last night. And this time it sounded like it came from the very rear of the motorhome. That was the first and only time I heard it come from the very rear. It seems to move around! But always a double knock, somewhat like a solenoid sound engaging and disengaging.

Yes! That is something I never thought of and that will explain why I hear it from different areas. Four different jacks in four different areas. But why a double knock every time?Does it only occur when the jacks are extended? Some hydraulic jacks make a pretty loud "pop" sound now and then when they settle some after being deployed. Sometimes the popping depends on how far the jacks are extended.
I've seen reports of both single and double "knocks" or "pops" that may just be differences in the jack construction. I had a backhoe/loader years ago that had one cylinder that always popped twice after awhile if I left the hoe boom suspended. A couple of jacks on our current coach pop once or twice now and then, other times not at all.Yes! That is something I never thought of and that will explain why I hear it from different areas. Four different jacks in four different areas. But why a double knock every time?

I think you figured out my ghost! It all makes perfect sense, especially the coming from different areas.I've seen reports of both single and double "knocks" or "pops" that may just be differences in the jack construction.
Retract the jacks for a couple of days and see what happensI think you figured out my ghost! It all makes perfect sense, especially the coming from different areas.
Looks like I will not need Ghost Busters after all!

There is no need. When I took my maiden voyage in this new RV to Cold Springs Station, NV, I spent more time inside this RV than ever (mainly to check things out and figure out how they work). At that time, I could not use my levelling jacks because the harness for the jacks was missing and on backorder.Retract the jacks for a couple of days and see what happens
Don’t you want to try testing it just one more time?There is no need. When I took my maiden voyage in this new RV to Cold Springs Station, NV, I spent more time inside this RV than ever (mainly to check things out and figure out how they work). At that time, I could not use my levelling jacks because the harness for the jacks was missing and on backorder.
On that trip, I never heard the knock-knock at all, and I was mostly inside the RV with no jacks possible to use.
There is a lot of evidence that it was caused from the jacks all along.
The very first time I heard it, it was at the RV park in Kingman. The next time, I was in ABQ in an RV Park. THen in an RV Park in Marianna. Then I heard it here. All four places I used the levelling jacks.
NY_Dutch spoiled our fun!
The big mystery is all solved. Thanks.
