yep, those are holdovers from the old days of tipouts/slides when the engineering was as good as now.
i've never heard of any newer RV needing supports for the slideouts, only that the manufacturers say no and you could void the warranty on the RV slide.
but since you didn't give any info on what RV you have, it's kind of pointless to speculate.
