My pipe-fitting purchases included a pack of white 1.5-inch slip-to-slip PVC couplings. I have grouped the straight-coupling options here.
The featured Amazon option is LASCO 1.5-Inch Slip Coupling.
Rigid Sockets or a Clamped Sleeve
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 water-tank openings were part of my early interior plan, before the later finishes enclosed the routes. The coupling purchase makes joint format a useful comparison. LASCO and Genova use rigid PVC bodies, while Fernco joins the pipe ends through a flexible sleeve tightened with clamps, changing the assembly around the connection.

Ends
Socket × socket
The LASCO 429-015 coupling joins two nominal one-and-a-half-inch pipe ends with sockets. Its straight body continues the pipe route without changing direction. Account for pipe engagement inside both sockets when laying out the finished length. A coupling measurement and the distance between exposed pipe ends describe different portions of the assembled run.
This straight socket coupling continues the route along one axis. Elbows and tees provide different route shapes.

Two Alternatives to Compare
The LASCO is a rigid slip coupling, and the Genova is a rigid repair coupling. The Fernco alternative joins plastic pipe with a flexible sleeve and clamps, giving it a different joint format from the two rigid fittings.
This Genova repair coupling provides a straight rigid connection for nominal 1.5-inch pipe. Its repair format offers another coupling design for comparing pipe joints.
This Fernco coupling joins nominal 1.5-inch plastic pipe with a flexible sleeve. Metal clamps tighten around the ends instead of forming a rigid socket joint.
