Tested Performance
Visual Highlights
Cooling Performance: The trailer started at 106°F inside after the walls, cap, and rear door had been soaking in Phoenix heat. The AC kept pulling the temperature down hour after hour until the cabin reached 79°F after five hours.(22:59)
Power Consumption: The Victron 500A SmartShunt readings ranged from 393W on fan speed one to 897W in turbo mode, with fan speed three measured at 577W during the hottest part of the test.(24:01)
Solar Compatibility: The old Coleman stood a little over 14 inches tall, while the OutEquipPro installed at about 7 inches. The shorter profile reduced solar shading and opened roof space for a 600W panel layout.(5:53)
Weight Savings: The roof-mounted Coleman parts came in at 85 lb. The OutEquipPro roof load, including cable and accessories placed on the roof, came in at 50.14 lb.(14:18)
Noise Level: The finished installation let normal conversation continue while the AC was running. The old rooftop unit had been loud enough to dominate the cabin.(30:20)
Serviceability: Under the cover, the unit used a modern control module, brushless motor setup, scroll compressor, R134A refrigerant, and low-side and high-side service ports.(7:28)
Recommendation: The final setup suits compact trailers where lower roof height, lower draw, and more solar area matter more than oversized single-unit cooling for a large RV.(32:30)
Detailed Analysis
Phoenix Heat Made the Old Roof Unit Feel Like the Wrong Tool
The owner tested the project in Phoenix, Arizona, where the trailer had to deal with a 115°F day, 160°F asphalt, and interior surfaces that had already stored a serious amount of heat. The R-Pod 153 is a compact travel trailer, and its weak insulation made the job harder than simply cooling cabin air.
The factory Coleman unit had two practical problems before the cooling test even began. It pulled around 1400W, and its tall rooftop shell blocked solar production during valuable parts of the day.
- The old rooftop unit stood a little over 14 inches tall.
- The replacement OutEquipPro 12V rooftop AC measured a little over 7 inches installed.
- The smaller footprint created enough room for a planned six-panel, 600W roof solar layout.
- With tow-vehicle solar included, the owner expected close to 1000W of combined solar.
That is the real decision point for small trailers. A lower-draw 12V AC is not only about comfort; it changes whether the roof can carry enough solar to support the system during normal camping conditions.
The Hardware Felt More Modern Than the Factory Coleman
With the top cover removed, the OutEquipPro presented a cleaner, more serviceable layout. The owner identified the controller and inverter module, fan assembly, condenser, scroll compressor, and accessible service ports.
- Refrigerant was marked as R134A.
- The unit included low-side and high-side fill ports.
- The observed construction included brushless motors and a scroll compressor.
- The older Coleman used 410A and was not presented as a simple rechargeable setup without tapping the lines.
The hardware comparison matters because rooftop AC units live in heat, vibration, and service-constrained spaces. Easy access to the control module and refrigerant ports gives a small-trailer owner a more practical ownership path if maintenance is needed later.
The Basic Install Was Simple, but the Thick Roof Changed the Job
The install kit was straightforward: interior panel, studs in two lengths, washers, split lock washers, nylock nuts, wiring plugs, gasket material, and dense support foam. The owner also used Henry 884 sealant around the roof seal area.
The main wiring and connector work was simple. The positive and negative leads handled the power side, while the interior panel connectors matched up one-to-one. The temperature probe was routed over the fresh-air inlet, and the remaining wiring was tucked into the panel space.
- The factory rooftop unit was removed from the existing opening.
- The OutEquipPro gasket and support foam were positioned around the 14x14 roof area.
- The owner modified the dense foam placement to avoid blocking condenser airflow.
- The interior metal plate and panel were pulled against the rooftop unit with the supplied studs.
- The wiring plugs were connected and cleaned up inside the ceiling panel.
The main complication was roof thickness. The R-Pod roof measured about 4.5 inches, while the standard installation was described as fitting up to 3.5 inches unless an extension kit is ordered.
That extra inch created a real fit issue. The longest studs barely reached, the split lock washers had to be omitted, the studs were backed out for more thread length, and the interior trim had about a 1/8-inch gap that needed aluminum duct tape to separate hot return leakage from cold output air.
Cable Length, Breaker Size, and Wire Gauge Became Part of the Real Cost
The unit arrived with attached 6-gauge cable. The measured cable length on this July 2026 unit was 15 feet 8 inches, which was longer than some reported lengths the owner had seen elsewhere.
For a real installation, the owner did not treat the AC as a single-box swap. He laid out the supporting electrical parts needed to make the 12V load behave properly.
- At minimum, he recommended 2-gauge red and black cable for the longer battery-to-distribution run.
- He used a 120A breaker near the positive battery terminal.
- He recommended a positive and negative distribution block with heavy studs.
- He listed cable clamps, truss-head screws, zip ties, extra lugs, a hydraulic crimper, VHB tape, a dual-gland roof entry, and roof sealant as practical install materials.
- He bypassed the stock converter and used an 80A charger for shore-power or generator charging.
The only electrical criticism was wire gauge at high output. In turbo mode, the owner saw a little over 1.2V drop between terminal blocks and the AC unit, and he felt a 4-gauge factory lead would have been a better match for that use case.
The Torture Test Was Slow, Consistent, and Useful
The cooling test started with the trailer at 106°F inside. The walls were around 100°F even without direct sun, the rear door reached roughly 122°F to 125°F, and the surrounding pavement was measured at 160°F.
| Runtime | Cabin Temperature | Practical Reading |
|---|---|---|
| Start | 106°F | Heat-soaked cabin and contents |
| 1 hour | 93°F | Cold airflow was already noticeable |
| 2 hours | 90°F | Temperature kept dropping despite stored heat |
| 3 hours | 87°F | Cabin began feeling comfortable to the owner |
| 4 hours | 83°F | Heat recovery continued in extreme conditions |
| 5 hours | 79°F | Final result reached usable comfort range |
The important part is not that five hours is fast. It is that the unit kept moving the number down in an extreme test where the trailer structure, cushions, bed, walls, and door were still releasing heat into the cabin.
For the owner's real camping pattern, this result matters because his family usually camps in conditions closer to a 90°F high, not 115°F Phoenix pavement heat. In that more normal range, the same AC would have far less stored heat to overcome.
Victron Readings Put the 12V Power Story in Real Numbers
The owner measured AC draw with a Victron 500A SmartShunt, which makes the power section more useful than a loose estimate. The readings were taken in severe outside heat, so they represent a demanding condition for the compressor.
| Mode | Measured Draw | Use-Case Meaning |
|---|---|---|
| Sleep | 433W | Low-speed comfort range |
| Fan speed 1 | 393W | Lowest measured cooling draw |
| Fan speed 2 | 416W | Likely overnight maintenance range |
| Fan speed 3 | 577W | Practical running range for this trailer |
| Fan speed 4 | 753W | High-output cooling |
| Fan speed 5 / Turbo | 897W | Peak draw near 70A |
For this small trailer, fan speed three was treated as a realistic working level after initial cooldown. The owner expected fan speed two, around 416W, to be a reasonable overnight maintenance point once the trailer was already under control.
The Final Recommendation Was Positive, With Size Limits
The owner's final answer was practical. He would choose the OutEquipPro again for this camp trailer because it reduced power draw, reduced roof shading, opened space for six 100W panels, removed about 35 lb from the roof, and ran quietly enough for normal conversation.
He also separated small-trailer success from large-RV expectations. For a single AC on a 24-foot to 25-foot or larger trailer, he would not choose it as the main cooling solution unless the goal was only to reduce the temperature by a few degrees.
The caution list is just as useful as the praise:
- Make the extension kit requirement obvious for roofs over 3.5 inches.
- List the installed height as a little over 7 inches, not 5.5 inches.
- Represent roof weight closer to 50 lb with roof-mounted accessories, not only the lighter base figure.
- Consider heavier factory wiring for turbo-mode voltage drop.
For compact trailer owners trying to build around solar, battery capacity, roof space, and livable cabin noise, this is the kind of trade-off that makes sense. It is not positioned as a universal replacement for every large RV roof AC, but it fits the R-Pod 153 use case with unusually clear data behind the decision.
