Default When to dump suspension

New owner here, just bought this SP36. Typically, when should I dump the suspension? I guess I'm asking, if I plan to be parked for X hours, no reason to dump but if more then Y hours then yes dump the suspension.

If it holds just fine for days and you don't mind the step-in height it doesn't matter if you leave it aired up indefinitely. A lot of times when they start to come down from losing air over time one end will go down faster than the other, though.

The rear will get soft overnight unless it's absolutely dead level, which it never is. The HCVs are all most likely original, with all new valves and DOT fittings maybe it would hold, but as Aux air goes down in 5-6 hours (as with most vintage BBs) this probably has an impact on suspension air.

With this coach, I tended to try to set jacks if I was going to be somewhere suitable for more than a day (and it's more or less level) and then let it down. My procedure was to set fronts to raise very slightly (as nose is a touch lower in riding down the road mode), then set rears just to touch, then dump, then adjust, usually need to drop nose slightly, I went by the LaserLevel app on my phone more than the blinking lights. Old paddle levers make this easier than automatic HWH, which is nice in the case of 89173.

I usually dump suspension then set my jacks to level the coach. Minimal extensions of the jacks and easy to to step up into and easy to prepare to go.

The coach is more stable with bags dumped--when people are moving around in the coach, it makes the coach bobble around if up. I'd guess jacks make it more stable too but I dunno, I never use the jacks. The SP jacks are constructed lighter than the tag coach jacks because the tag coaches are heavier. Rumor has it the lighter jacks can leak due to flexion? Again, I don't really know.

The jacks on my (Bobbie's) SP looked no different than the ones on a 92 WB40 that sat next to it for a couple months. Sure about that? I don't think any HWH jacks leak due to anything but ancient seals. Now these Bigfoot things on the M380 are another matter!

My HWH jacks have been up now for 10 months...

Waiting for the house to be ready so I can move back in.

I dump the air, hit the HWH on button twice, and let it level the coach, then turn the engine off. Works for us.

Bobbie has my old SP36 with manual paddles, no automatic.

OK. When I used our SP I dumped the suspension, using the "paddles" I touched the ground with the lowest side jack, and then the next in turn until the coach was level. Use my phone as the level bubble. Always dumped the air before trying to level.
