I have a 2004 Phoenix Cruiser 2350, and have never had the shavings problem during use, but I would suggest looking for any places that could have trapped left over shavings from when the RV was manufactured. Over time, the shavings just shake loose and show up on the floor. I have found small amounts of shavings in other places, like in the light fixtures, just due to the installation processes. Once I completely vacuumed out the shavings, I haven't been bothered much since. We also use a 4 ft x 6 ft area rug in front of the slide out to help keep the dirt contained in the living area. When we are packing up, we just take the rug outside, shake out the dirt, and roll it up to store it. This helps on the bare feet. If you really think the shavings are due to metal-to-metal contact during slideout operation, try lubing all of the contact locations with a spray-on lithium white grease. The spray-on type helps to ensure that you will lightly coat surfaces in the hard to reach areas, and it's very easy to apply often. I have been using it on my slide out screws and hinges for a couple of years with good luck. If this doesn't solve the problems, post again and I will try to help some more.
