Thank you for providing that information. According to Lippert, you have a 1621 pin box rated for 15.5k. When choosing a replacement you want to make sure you match up the bolt pattern and the rating. Since Reese has been out of stock for months as of June 2023 with no word on when the goose box will return, I recommend getting the Gen-Y instead.

The Gen-Y Hitch 5th Wheel to Gooseneck Pin Box has similar performance using a rubber torsion system instead of an air bag. I'm not entirely sure which 2022 Keystone Avalanche you have, but it looks like the GVWR varies from 15,000 lbs up to 16,500 lbs. Based on that information the correct Gen-Y is the # GY38FR. You will also need safety chains # GY49GR since they are not included.
