Well it wasn't near St Louis but I found RVincidents in Nixa, Mo to do the flooring install. Price was on the high side but they did a great job. Replaced the carpet in the bedroom and front of the coach and installed vinyl plank flooring in the rest of the coach including the step well. Big selling point was a shop with indoor work areas and a special lift to remove the slideout.
