Metal plates under sofa slideout
We were doing a little cleaning checking out our Vegas 24.1 before a trip.
the slide out holds our sofa bed and I noticed 2 long black steel plates about 24 inches long and 8 inches wide on the slide out floor under the bed.
Can I assume these plates house rollers of some sort that are part of the slide out? If so any routine maintenance required there? Would actually have to remove the sofa to get them out.
