While unfortunately I don't have any way of knowing specifically what wheel caps are on your Arctic Fox 5th wheel, it's pretty easy to determine what you need. Just measure the center bore from inside to inside of your wheel. For example, the Americana Trailer Wheel Center Cap # AM90077 is for 4.25" - 4.27" center bores and fits 15" and 16" diameter wheels with six bolt holes.

If you aren't sure the diameter of your wheel, take a look at your tire size (which is labeled right on the tire). If you have a 235/85R16 tire, then your wheel diameter is 16 inches. I have added a link below to our selection of center caps for you as well.
