You said new so I take this was warranty work. I can tell you the RV repair tech I know and have meet at Camping World are top rate individuals. If this was warranty work the manufacture makes all the decisions not CW. The staple size was probably the size told to CW from the manufacturer. As far as the paint this is a manufacturer recommendation since they always say paint and see if the customer finds the problem. I've seen rigs sit for weeks because the color the manufactures says it was painted does not match. Glad you have it fixed for the camping season.
