I hope this guy is way behind me on the highway
My dealer did the screws threw the slide floor when moving the dinning table during a slide out adjustment on my Lacrosse. Thank God I caught it on my inspection of there work.
(Past experience taught me well)
They also did the screw threw the slide floor on my Tracer when doing repairs to my bench seating. This tore up the plastic threshold, snagged the carpet and cut the wiper seal.
But then again I always try to inspect all there work closely now.
