DEWALT DCS380B: Cutting My Heater Floor Opening

My DCS380B helped turn a marked heater location into an opening through the van floor. The job also involved starter holes, grinder work and finishing the cut edges—and two broken metal-cutting blades.

What Matters for This Job

  • I marked the opening from the heater mounting plate.
  • Two metal-cutting blades broke during this job.
  • Both alternatives are corded saws; blade arrangement is another difference.

The Build Behind This Item

Removing the passenger seat gave me access to the heater location. I marked around the mounting plate and started the opening with a drill before using the reciprocating saw and grinder to remove the rectangle.

That sequence is more useful to me than treating the saw as a one-tool solution. After the cutting came edge finishing, primer and white paint, followed by the heater fittings passing through the floor.

Making the Floor and Seat-Platform Openings

  1. I drilled a starter opening using the marked mounting-plate layout.
  2. I used the saw and grinder to remove the floor rectangle.
  3. I cut the seat platform, removed the interfering handle and finished the edges.

Camper Van Project Applications

A reciprocating saw is useful for removal work where the cut is larger or less delicate than a jigsaw cutout. Blade length and the space behind a panel affect access. For van sheet-metal openings, compare the whole cutting position rather than assuming a stronger tool alone makes a more precise cut.

My Experience with This Tool

I did not use my reciprocating saw as often as the grinder or jigsaw. One larger job made its value clear: cutting the openings in the rear cargo-area sides for my bed capsules. I first tried the grinder and jigsaw, but both felt slow and took more effort than I wanted. With a metal-cutting blade fitted, the DEWALT reciprocating saw cut through the van siding much faster.

Once it was moving, the saw took more attention to control. I was still able to follow the lines I had marked for the capsule openings. It became my choice for bigger cutting jobs that needed more force and speed.

I built much of the van on the road, carrying tools and materials in a trailer and working outside. Durability is the main reason I consider my DEWALT tools worth the money: they kept working through dirt, travel and rough handling.

My Takeaway for Choosing the Kit

The blade breakages are part of my experience with this opening. I would compare the saw, the blade selection and the available cutting space together. The cordless DCS380B kept a power cord out of that arrangement; the DWE305 and SKIL alternatives make mains power part of the setup instead.

Two Alternatives to Compare

The DEWALT DWE305 and SKIL 9206-02 are corded alternatives to my cordless saw. The DWE305 adds a four-position blade clamp to this comparison, while the SKIL provides another variable-speed corded arrangement. Power supply and blade-position options are the useful distinctions here.
