Well, today is the day! I'm heading out to see the coach for the first time. The owners have graciously offered to let me stay overnight in it for the next 48 hours prior to our drive to Nac for the PPI. I found some great self-PPI resources on the forum that I'll use to go over systems during the next 2 days. Then we will see what the professional finds.

Thanks for taking time (in this thread and over on a current bulkhead inspection / repair thread started by Mike) to help this newbie understand some of the issues surrounding bulkheads. I didn't realize at first that the bulkhead is the center component of the sandwich. I kept asking if I should paint it because I imagined that it was an exposed structural element!

I can't thank all of you enough for your patience, kindness and suggestions.

Thanks,
Mark

Very nice coach. What is included in "We spent an additional $14,000 after purchasing the coach for a complete service with a Foretravel dealer in Texas who gave the coach a good report. "

I need to read the posts more carefully. Little things add up fast.

Good pointing to the last service list - I hadn't read through it that carefully, either! If no record of it since that service in 2015, the coach is due for an air dryer service (or better yet replace with a DA33100X Haldex-done reman from NAPA so you start with a known-good set of internals).

(do a forum search for air dryer powder and you'll see why

)

I'm here in the coach.

There's a receipt from NAPA dated Jan 2016 that includes:

-- Qty-2 of NAPA 109994K Air Brake Dryer Repair Kits - H/D Truck Bendix ADSP Desiccant Cartridge - New HALDEX
-- Oil
-- Oil, air, coolant and fuel filters
No mileage on the receipt but it make that service 15 months ago.

-------------------

So far the coach looks nice. Going through it a little at a time. I'm excited and a little nervous!

Inside maybe a 7-1/2 to 8
Outside about the same. Paint is beautiful. To my newbie eyes, no indications of delamination.
Roof very crisp and clean. Has some kind of grippy stuff mixed in with the roof coating that FOT applied.
New Michelins look good
Cummins starts easily and runs smoothly

Minor stuff not working -- mirror turn signal out, one marker light has only one bulb working instead of 2, left headlight low beam inoperative, one of 2 radio speakers over couch out. Little stuff like that.

All 3 AC's work in cooling and heat pump mode. Generator starting and running smoothly.

Bigger stuff not working:

-- Aquahot --- works on on 110VAC but not on diesel.

-- One of the air tank drain valves behind the driver side front wheel had maybe a quart or 2 of water in it. It was the valve closest to the outside edge of the coach. The other 2 and the drain at the rear tire were pretty normal -- just a little mist.

-- Propane tank is empty. Dometic refrigerator not cooling on auto setting with the generator running. Check light is on.Slides work smoothly.

-- The Silverleaf screen with the rotary knob and the 10 buttons is completely dead. Fuse?

More to come...

Fridge will not cool down that fast to tell if it is working or not... unless light is off but should go into (limp mode?) it will blink I believe if there is a problem.. it will take hours for the fridge to cool.. like overnight or 8 hrs...

any pics? Or link of which you are looking at? Maybe I missed it?

Nvm I see this is page 2 and missed the 1st page with the link.

There should not have been water in the air tanks.

How do I get the 50A electric reel to retract? I see a button for the water hose reel but not for the power.

Thanks!

If now switch for the reel it might need a quick pull and let go.. might not be electric .. if it is electric there should be a switch right there in the electric bay

Looking at the pic for the reel.. it looks electric.. should be a button in there to retract

The drain valve with the water coming out for the air tank is for the tank for the hwh compressor, there is no dryer on it so will need to be drained frequently also the switch for the electric cord should be beside the switch for the water pump and the water fill in the utility bay.

Thanks friends. Found that switch and got the shore power reeled up.

Found a logbook with every oil change, air & fuel filters, genny service etc. Looks super good. Oil & filters changed every 3k to 5k. Genny serviced at each 250hr interval.

Coach is from Las Vegas -- a dry desert coach.

As for your fridge... It looks like a Dometic 1492.... ours was erratic on cooling evenly with the propane side "dropping out" when traveling in the mountains.. just did swap it out for a Samsung domestic @ MOT...... my ice cream sammiches are now well and fully FROZE!
bought the Samsung fridge @ Sears & MOT did a really good job with the woodwork filling the gaps & modifying the lower cupboard.
Will be in Nac for the next 3 weeks.( @ Old town & 2 weeks @ Xtreme) stop by if you want.

Good morning. Should the small struts on the overhead cabinet doors (throughout the coach) be able to hold the cabinet doors in the open position? None of these do so. When I open each cabinet door it falls back to the almost fully closed position.

Yes.

They are about $9 apiece at FOT parts. (MOT might have them, too) The brand is Suspa. The price is competitive with cheap knockoffs and the cheap ones can cause the mounts to pull out of the cabinet box.

They do wear out (there was a recent discussion about mounting them so the rod was low and the cylinder high to keep the seal from drying out).

Silverleaf is up and running. History available back to 2012.

Silverleaf Stats:

Only engine diagnostic of any concern is the engine coolant reported as 220F @1800 RPM once a few years back.

PIAB Air Leak

Reply #44 – April 30, 2017, 12:17:38 pm

In the basement compartment containing the aux. compressor, inverter, etc. there are two items labeled PIAB. While they are obviously part of the compressed air system, I've searched and haven't found their function. The unit on the right of the first photo (closest to the centerline of the coach) has a significant air leak in the valve shown in photo 2.

What does these PIAB units do?

Will this leak impact driving safety? Supposed to drive to Nac tomorrow for the PPI.

Thanks,
Mark

Those are for the bladders.. the valve shuts off the air to the bladders.. swap out, if the valve is leaking. Strut part# off mine is c16-21696 ..I had one sitting on my desk that I replaced.. cheap online also

Mark,

Those valves have 3 O rings on the stem. It is a simple process of just pulling the stem, installing new O rings, and putting the stem back into the valve body. The engine driven air compressor should be able to keep up with no problem. That is a leak that will cause the little 12VDC air compressor to overwork and burn it up so the leak needs to be fixed.

David -- Indeed the fridge did cool down overnight and there's ice in the freezer!

Mike, do you know if the o-rings are common NAPA items or special order from the manufacturer?

Thanks,
Mark

Mark,

They do have OEM rebuild kits that have the O rings and a little tube of silicone lube, but they are just a standard size that can be purchased most anywhere that has O rings like any auto parts store, Ace hardware, or even a hydraulic store. I have replaced several for various members as this is a common problem.
