A single-gang metal box is among my electrical-enclosure purchases.
The featured Amazon option is Sealproof 1-Gang 3 1/2-Inch Holes Weatherproof Rectangular Exterior Electrical Outlet Box with 3 Outlet Holes, Three 1/2" Holes, Single Gang, UL Listed.
Where it fits my build
I brought the roof light wires and camera cables into a PVC conduit layout. That work included drilled enclosures, threaded fittings, cable glands, solder-seal splices and grouped wiring.
During the small-box stage, I drilled for a male PVC fitting and used a fitting inside as a retaining nut. I routed the camera cable through a gland into a tee and brought the light-wire groups toward the van entry.

My build notes
The wiring project was a sequence of individual connections and routes. The photographs show the intermediate stages, including open boxes and wrapped wire groups, before the remaining covers and conduit joints were finished.
I built the cable route a section at a time, bringing local connections into the larger conduit system.
