Hi Wayne, I am pleased to assist you. The primary difference between the Curt Class IV hitches #14017 and #14021 lies in their cross tube design, which affects both aesthetics and price. * 14017: has a straight cross tube design that's fully visible under the rear bumper. It’s more traditional and is often marketed as a rugged, heavy-duty option. * 14021: has a curved cross tube that offers a cleaner look with less of the hitch showing beneath the bumper—usually seen as the more “refined” style. So why the price flip? It often comes down to inventory levels, or discounts on one model over the other. 14017 is discounted at 38%, while 14021 is discounted at 81%. Sometimes, a part with better aesthetics ends up being priced lower simply because it's overstocked or on clearance. For your 2023 Ford F-150 XLT V6, both hitches are compatible. If you prioritize a more discreet appearance, the #14021, with its concealed design, would be suitable. Conversely, if you want something straightforward and functional, and visibility isn't an issue, the #14017 would serve you well.​ Let me provide you with both links below so you can choose which one you'd prefer to order while parts are in stock. I hope this helps.
