Replacement Lug Nuts for 2022 Keystone Cougar 316RLS

Question:

Hello. I own a 2022 Keystone Cougar 316RLS. Ive had a couple wheel lugnuts become somewhat deformed. Can you advise if there is a specific lugnut size for RVs? There is 1/2 inch stamped on the side and the length appears to be 1.4. Thank you.

Hey Rick! There are a few potential sizes but 1/2" is pretty common. You can double check and measure your wheel bolt size if you want just to be sure but, with that 1/2" on there I'm sure you can use the Chrome Trailer Wheel Lug Nut # 12CLN. These are 1/2"-20 with a standard 60 degree cone and measure 1-3/8" long just like the ones you have now.

Hey Rick, how did the new chrome lug nuts work out on your Cougar? Did they fit the wheel studs the way you expected? Your update could make it easier for the next person with the same issue.
