Tiffin Slideout

We brought our new Phaeton Tiffin Motorcoach home and found, after leaving it leveled with all slides in, that the passenger side bedroom slideout comes out about 2-3 inches from the side of the coach (over several minutes) after we had retracted it in to where it was flush with the coach side. I have tried releveling, putting all the slides out and retracting them again, but the same thing keeps happening. We have notified the dealer today (after hours) and are waiting to hear back from them. Just wondering if anyone out there has experience with this problem and has any suggestions.

If it is an hydralic system I would say it needs bleeding. There is a procedure for removing the air by holding the button in the out position for a few seconds after full travel of the slide. If electric the brake lever on the slide motor may be in the wrong position.

The 40QTH has a mechanical slideoput on the DS and an HWH hydraulic slide on the PS. The mechanical slide has a clutch on the motor and is located beneath the bed. Sometimes the release lever gets bumped and the slide can freewheel. The same holds true for the big DS slide in the living area if you bump the lever with basement cargo.

In this case the PS slide is hydraulic. It is possible that there is air in the system. and that it may need to be bled. It's also possible that a solenoid valve is bad and not seating. A third possiblilty is that there isn't enough juice in the reservoir and you can't get the air out of the system. The reservoir for that system will be found in the front cap, just ahead of the steps so you need to crawl under the coach to access it. Our '07 Bus has two systems - one in a basement ciompartment for the leveling jacks and the one in the front cap for the slideouts.

One thing to keep in mind when checking hydraulic fluid levels:

Hydraulic system fluid levels always need to be checked when the hydraulic cylinders are fully collapsed. This sometimes gets confusing to anyone checking the slideoput system because the cylinders are collapsed when the slides are fully extended. So, you need to check the fluid level when the slides are out, not retracted. If you fill the reservoir up when the slides are in you'll have a big mess on the ground once you extend them. This is just the opposite of the leveling jacks, which need to be checked when they are retracted.

Slide creepage

If your slides are electric drive like mine, there is a brake device on the motor/shaft that may be in the unlocked position. Go to website for your slide drive system [HWH?], to see the description. Setting the brake stopped my slide creep problem. It is a matter of rotating a lever with your finger.
