On my way to US, what's a good place to stop for filters?

[MEGA HO]

Heading to the States picking up a truck camper. Figured I'd stop grab a few sets of filters for the trucks as for whatever reason it's so hard to find proper filters unless I buy from a dealer at the ridiculous prices.
O'Reilly's? Docs filters? Just a few names I heard here in there.
We are heading to Maple Valley in WA if that makes any difference.

Thanks all in advance!

There’s a couple fleetpride locations in the Seattle area. Call ahead to check for filter availability. Usually if my local one does not have what I’m looking for they will bring it in from another warehouse.
