If your 2006 is the same as my 2012 Lexi 283ts...
In the storage compartments below the two front slides...when you open them, look up to the top of the compartment. You should see a protruding hex bolt on a shaft sticking stright down. Those are the manual bolts to bring the slides in/out. Takes a 5/8 inch socket or wrench.
Bedroom is a different problem. Lift the matteress to access the area under the bed. Toward the head of the bed area, you should see the slide mechanism and its attached motor/gearbox. Sticking out the side of the gearbox you should see a hex bolt held onto a shaft with a safety clip (if like my Lexi).
That hex bolt is the manual bolt to bring the slide in/out. Stupid design, as you have to bring the slide in/out while the matteress is up. And when you get it in, there's not enough room to let the matteress down.
I actually think the designers of rv's lay awake at night just thinking up ways to make it almost impossible to work on these things.
It's obvious that the people who design rv's don't own or have never owned one.
