Try running a wanted add on craig's list. I was looking for a pump last year and got a couple calls from guys selling whole systems off salvaged units. Mine turned out to need a couple 25 cent washers that melted under the ground terminal due to a loose ground connection.

Mine has them, but my gut feeling is they were added aftermarket because they are mounted completely different to every other I have seen.
I have used them, and my Jacks are more than capable of lifting my 345 off the ground... and I had it roll off too... I was inside... that was a wierd feeling... and I was on level ground too!
Anyway, I know I can hear/sense my chassis flexing when I use them, but I have to say that if the frame is flexed, they are not being used properly!
I looked mine up and each corner has a 9000LB rated kickdown in each corner.

I think if they were not there, I would probably not spend the money on buying some!

Here they are in action on a nose down pitched site in AZ.

Mine flex the chassis enough that the door won''t open(if closed) and won't shut(if open)...they ARE advertised in the original papers as LEVELING jacks...m
RV Andy swears they are stabilizers, only...My experience, his wisdom...well, I'd have to go with Andy...

Just a quick comment from a factory authorized HWH service center. I have never seen HWH jacks used as anything but levelers. In the newer models that use jacks, they are referred to on the control panel as "HWH Automatic Leveling".

On trailers; stabilizers due to the nature of the thinner frame but on a motor home; LEVELERS.

Of course there are times when, due to 'excessive slope', one must use blocks under the tires, but on fairly level ground it should be no problem.

I have the Power Gear hydraulic leveling jacks on my 82' 280. They are not stock...my dad installed them at some point. They will lift the mh off the ground. I have the three jack system. I've read everything there is out there on which is better, three or four...mine work just fine.

Rarely do I park on a level space, but I do use the yellow plastic Legos such as Derek mentioned. I level the mh as best as I can first...no big deal really. If I don't, even on my short 280, I will jam the entry door if I just use the jacks on an excess slope.

When I recently rebuilt my rear airbag system (compressor, tank, lines and bags) I also installed a dump valve on the rear bags but haven't wired it to power and a switch yet. Could have used it on my last trip!

I can't say if it's jack placement or maybe the longer wheelbase of the 34.5 but my HWH never bind the door or anything else. I have put a bottle jack forward of the rear axle on the frame and it will bind the door as soon as there is a load on the jack. Never a problem with the levelers. The only problem is if you raise the rear too much and it rolls off the jacks. The first time it really gets your attention. You really don't want to do it a second time.
BTW I did use the HWH mounting brackets for the P-30.

Cheers, Dan
