Hi Don (and Van),
Thank you for your suggestions here. The slide depth was easy to set. I moved the slide out about 2" from full retract position and though hard to see, it was easy to find the carriage bolt heads by feel. I loosed the jam nuts and threaded in and out the stops.
After a few iterations, I had the slide depth set to my satisfaction.

On a related topic...
I had a weird scenario where the slide seal didn't seem to inflate (I could see 1/8" strip of light adjacent to the slide at the front coming from the inside, while I was camped for several days and while I was driving I could hear substantial wind noise.

It does seem to be inflating and sealing now. I can't explain the inconsistency.

Even though the seal wasn't inflated, it did have pressure @ 18 psi based on the gauge in the slide control panel. It does hold pressure, too. So I don't think it was leaking.

Cheers, Doug

Setting slide seal pressure is about adjusting PSI to sweet spot where no light shows through the seal when inflated, but not higher. The value I gave is where that happens on mine.

Hi Van,
Appreciate the thoughts. I think I'm not communicating well.
For now apparent reason, I had a 1/8" gap that whistled as I drove. I actually cranked to 30 psi and the seal didn't inflate any further.

Then, it seemed to work. Now with 18 psi I have no gap.

It was almost like the line feeding pressure to the seal was kinked or blocked for a few days. I'm guessing there is a solenoid. Maybe it didn't open pressure to the seal??

Doug

Default M380 Living Room Slide seal

Doug W

Be careful raising the slide seal pressure, as our seals age the high pressure can cause a rupture and leak. If you have or see an airgap first go down in the bay where the air control is. You will see two gauges the one to the left is for slide actuation, the one to the right is seal pressure. The lower seal pressure the better for seal life but it is a balance for seal contact also. On mine I have 15 lbs. Just to the right of the seal pressure gauge you will see the seal control valves, the far right one is the bed room seal. The first one is living room. On the base of the valve if it is in the deflate mode you will see a red light. When inflated the light is out.

Good Luck

Gump

Hi Jacob,
thank you for the additional info. I reset to 18 lbs after a quick 90 seconds @ 30 psi to see if I could close the gap. I failed to check for lights as I was in a hurry.

Maybe I'll look at 15 psi.

Next time, I will check out the lights. I know when I drove it back to storage today, the seal was inflated as I didn't hear the road noise.

In the end, I camp usually in temperate climates, so a little draft or mixing outside and inside air isn't a big deal. So I'll choose to preserve the seal.
best,
Doug

Is it possible the problem occurred when the slide was pushed in a little? It isn't supposed to inflate if in from the normal stop position.

Hi Don,
I think the issues are probably related though I don't exactly know how (to my knowledge, the slide was in its normal retracted position, though it was 1/4" too far.)

We had camped one night in a canyon above Pt Mugu State Park beach. The wind was howling that night. The site was extremely unlevel. I struggled to get level with the jacks and blocks.
The strong crosswind actually blew the slide in twice. I was surprised to say the least.

During the same adventure, I think I drew air in to the rear leveling jacks since they were slightly low and at one point each jack far extended. So later I ended up having to refill fluid and then bleed the air out to get them working again. For a day or two they wouldn't extend or retract consistently.

Live and learn!

I've attached a photo of the M380 Mountain Goat.

Thanks for everyone's thoughts here.

Doug

I've experienced the light gap on my M380 that I think it was caused by a sticking solenoid valve. I disconnected the control wires and reconnected them. It seemed to solve the problem.
