Not sure about RV sales, but most car dealerships have two rungs of sales staff. A few who have managed to stay around awhile, are good at it and the rest. My dad who owned a string of Real Estate brokerages always said 10% of the sales people make 90% of the money. Car dealers rely in large part on young and dumb wannabes with stars in their eyes who hire on and in the first month or so sell a car to their brother, sister, mom and aunt before realizing they aren’t any good at it and are on the draw for a few weeks before the dealer kicks them to the curb. They only thing they may learn is how to turn the radio on and how to take the worksheet to the sales mgr. so he can refigure the four square and make it look like you aren’t buying your own trade.
