Detailed Analysis
45 lbs: light enough for a thin aluminum roof
The OutEquipPro 12V AC unit weighs only 45 lbs – light enough for a thin aluminum roof that would never support a conventional 110V RV air conditioner. That low weight, combined with a standard 14x14 vent opening, made this the perfect fit for a 19-foot enclosed ATV cargo trailer with no reinforced ceiling framing beyond standard 24-inch on-center supports.
Gasket fitting: cutting and repositioning for a perfect seal
The kit includes a foam gasket that unfolds. The owner initially placed it around the hole, but discovered the gasket was larger than needed. More critically, the gasket has integrated hard plastic spacer tubes that prevent over-compression when the AC is tightened down – they allow a few millimeters of crush but stop before the seal fails.
After a dry fit of the AC unit on the gasket, the owner checked from inside the trailer:
- Saw light coming through at the rear corners – meaning those openings were inside the gasket and could allow water into the ceiling cavity.
- Also saw light through small holes in the bottom of the AC unit that needed to be outside the sealed area.
- Solution: Cut the gasket on both sides (removed about 2 inches from each side), then slid the gasket forward so the back edge was flush with the roof opening. This pushed the drain ports and bottom holes outside the sealing ring.
- The gasket still had good adhesion even after repositioning – no need for new adhesive.
Once the gasket was correctly positioned, the owner added the two additional foam support spacers under the rear of the unit (to fully support the AC's base).
Wiring pass-through: notching the gasket
The power cable exits the bottom of the AC unit. To route it cleanly:
- Notched the back edge of the foam gasket to create a channel for the 12V wiring harness.
- The notch was sized slightly tight so the foam would compress around the cable when the unit was lowered – creating a natural seal.
- Later, the owner applied Dicor lap sealant around the entire gasket perimeter, over the notched cuts, and along the side seams where the gasket had been trimmed.
Interior brackets and the bolt trimming fix
Inside the trailer, the owner installed two metal brackets with four bolts that thread up into the AC unit. These brackets sandwich the roof framing, pulling the unit down tight against the gasket.
But the roof framing was only about 1 inch thick (standard 1x lumber). The supplied bolts were too long – they would stick down and prevent the decorative control panel (bezel) from mounting flush against the ceiling. The fix:
- Test‑fitted the bezel and marked where the bolts interfered.
- Removed the bolts and cut them off just above the nuts.
- Re‑installed the shortened bolts and tightened until the foam gasket was lightly compressed – no light visible around the edges.
The owner chose not to install the full trim ring because the trailer has no finished ceiling; the brackets and exposed bolts don't matter in a utility trailer. In an RV with a finished headliner, the trim ring would cover everything.
Cooling test: no insulation, aluminum roof, 30‑minute drop
The trailer is completely uninsulated – just wood walls, a thin aluminum roof that gets painfully hot to the touch in the sun, and gaps in the corners. This was a stress test, not a best‑case scenario. Conditions and results:
- Outside: sensor in the sun read 97°F, though the owner noted it wasn't actually that hot – but the roof itself was scorching.
- Starting interior temperature: 84°F with 45% humidity.
- After 30 minutes of running the OutEquipPro on high fan (not turbo mode), interior dropped to≈79.5°F – a 4.5°F reduction.
- After another 15 minutes (45 minutes total): 78.5°F, still dropping.
The owner was impressed that the unit could lower the temperature at all in a uninsulated metal box with no ceiling insulation and gaps letting hot air in. Walking inside felt noticeably cooler than outside.
Noise level: virtually silent outside
One of the most praised features: the AC is quiet. The owner said the only audible sound inside is the fan moving air – no loud compressor rumble. Standing outside the trailer, you can barely hear anything; the rooftop compressor is virtually silent. This makes it campsite‑friendly even in quiet hours.
Final note on power monitoring
During this initial test, the AC was temporarily connected to a 100Ah lead‑acid battery just to verify function. The owner has since upgraded to a 200Ah lithium battery and will monitor exact wattage, amperage draw, and runtime in a follow‑up video. Early impressions: the 12V DC design (no inverter loss) combined with the light weight and low profile make the OutEquipPro an ideal solution for enclosed cargo trailers, ATV haulers, and any thin‑roof RV that can't support a heavy 110V unit.
