I bought Camco Flexible Camper Sink Drain as part of my camper van equipment.
I bought the Camco drain assembly with my plumbing materials. My early interior plan linked drain openings to the later framing and floor layout.
The Route Beneath the Sink
I used SketchUp to plan the interior and put body openings ahead of the framing, floor and wall panels.
My Interior Preparation notes included the shower drain and openings for three water tanks in that preparation sequence.
I removed cargo tie-down hardware for later framing mounts and door trim for the later insulation and paneling.

My Takeaway for the Build
The early interior plan covered openings before the floor and panel finishes. My Camco sink-drain purchase puts the focus on the space between the sink and the outlet. A short flexible hose, an exterior evacuation fitting and a flexible P-trap represent different drain layouts, so the comparison begins with the intended route.

The 37420 is a compact camper drain assembly with a trap, flexible hose and evacuation flange. The exact-model retailer reference lists twenty-five inches of three-quarter-inch-ID hose. Those dimensions help assess the available route beneath a sink, where drawers, wall panels and nearby plumbing can limit space. The trap and flange are separate pieces with different materials, so the assembly can be identified more precisely than a generic length of drain hose. For a DIY van repair, the useful first comparison is the existing sink outlet, the route to the discharge point and access to the joints after cabinetry is installed.
The exact-model listing specifies a twenty-five-inch length of hose with a three-quarter-inch inside diameter.
Alternative products
Two Alternatives to Compare
JR Products offers an exterior evacuation trap with a different outlet arrangement. Cinsda uses a larger flexible P-trap format, making these alternative drain layouts rather than identical fitting replacements.
This compact black fitting provides an exterior evacuation-drain connection. Its molded body offers a different outlet arrangement from a flexible under-sink hose.
This drain assembly uses flexible tubing around a P-trap layout. Adjustable sections allow the route between the sink outlet and drain connection to change.
