That's a good question but we don't have a way to look that up since Winnebago does not list that as a spec anywhere. You'd have to measure and verify before ordering either the 3 inch # F02-2106 or the larger size # F02-2103.

Since the 3 inch size is the most common one there's a very likely possibility that's the size you need.
