NEVER believe the brochure!
water pumps usually are inside a interior cabinet, behind a cabinet "door" that is usually screwed in.
many of us simply add hinges and turn it into a true door, for easy access.
the water filter is usually mounted in the same cabinet.
rarely are they "easy access" except on 5th wheels or MH's.
