I can recommend Big Barker, we especially like the optional waterproof liner. We are up to 6 beds now including the home kennels, the SUV edition in the, uh, SUV, and the crate pads in the Sprinter. One was custom sized as a full size mattress shortened 6″ to fit width wise in the Sprinter, but it ended up being more useful as giant dog lounge in the living room.
