Tested Performance
Visual Highlights
Cooling Performance: The van starts at 85°F, then steps down to 72°F after one hour, 69°F after another half hour, and 61°F at the two-hour mark.(8:47)
Power Consumption: At the two-hour check, the AC is still pulling about 48A while continuing to cool the open van shell.(9:35)
Off-Grid Runtime: The display estimates 18 hours of operation at 63°F, even while the van is still a large open shell.(9:08)
Cabin Control: The remote, onboard light, swing vents, and 63°F low set point give the finished van a more usable cooling setup than a simple roof fan.(8:22)
Recommendation: Chris finishes with a cool van, a completed roof install, and a 12V unit he considers a strong value for the capacity.(9:42)
Detailed Analysis
The Box Sets Up a Bigger Job Than a Fan Swap
Chris starts the project around an open-shell van, which matters because there is no finished ceiling, insulation package, or hidden trim to soften mistakes. The Outequip 12V AC unit is presented as a larger unit than the compact models often seen in short social clips, and that immediately changes the install from a simple drop-in upgrade to a measured roof modification.
The package includes the AC unit, a template, foam brackets, hardware, an interior plastic piece, a manual, and a remote. The useful detail is not the unboxing itself; it is the template math that follows. The supplied opening reference begins around 14.1 x 13.7 inches, but Chris chooses a larger 18.1 x 14.1 inch cut for his roof layout.
- The standard fan-sized square remains a reference point, not the full answer for this larger AC.
- A pre-existing fan opening can be retained only if the surrounding mounting holes are added correctly.
- Without a pre-existing opening, Chris cuts the larger roof hole from scratch.
- Roof ribs become measuring landmarks, so the unit sits centered instead of drifting across the panel.
The Roof Cut Is Where the Install Becomes Real
Before cutting, Tara straps a trash bag inside the van to catch metal shavings. That small move keeps the interior from being sprayed with sharp debris while Chris drills guide holes and transfers the roof layout above. He uses a grinder instead of a jigsaw because he prefers its control, then cleans the rough edges after the cut.
The exposed steel edge gets paint before the AC sits down. That step is easy to skip, but it is one of the most practical details in the job: a roof appliance can cool well and still become a long-term problem if bare cut metal is left to rust.
- Drill guide holes from the measured roof layout.
- Cut the larger roof opening with a grinder.
- Clean the rough perimeter until the edge is smooth enough for sealing.
- Paint the exposed metal to reduce future rust risk.
- Test-fit the AC before committing to gasket and bracket compression.
Heavy Hardware Needs Two People and One Honest Test Fit
Chris is direct about the lift: this is a two-person job. The unit is heavy enough that placement, roof safety, and cable alignment all become harder if one person tries to manage the load alone. Once the unit is on the roof, the test fit catches a specific interference point around one bolt.
The fix is not dramatic, but it is useful. Chris grinds down the interfering metal area, then the bolt clearance is good enough to continue. Later, from the bottom side, he notes that cutting roughly another inch in that area would have made the bracket fitment easier for someone repeating the job.
- Lift with two people because the roof unit is heavy and awkward.
- Set the AC in place before sealing so bolt conflicts are visible early.
- Relieve the bolt area with a grinder if the bracket path is blocked.
- Expect the interior faceplate bolts and bracket bolts to use different mounting points.
- Plan for possible bolt trimming once a finished ceiling is installed.
The Gasket Work Decides Whether the Roof Stays Dry
The gasket has a sticky underside, and Chris starts it on a lower roof edge before working it around the opening. The van roof ribs create the real challenge. Each hole in the gasket contains a hard plastic insert that controls how far the gasket can compress, so the rib sections need careful trimming instead of random pressure.
Where the gasket lands on a ridge, Chris cuts the plastic insert to match that height, returns it to the gasket, and keeps bending the seal around the corners. At the final seam, both ends are cut to meet under pressure. He then adds roofing flashing across every crevice because the target is simple: no leak paths around the new roof appliance.
- Start the gasket on a lower roof section so the adhesive can anchor cleanly.
- Trim plastic inserts where roof ridges change the compression height.
- Keep the gasket ends tight against each other at the seam.
- Use roofing flashing to seal crevices after the gasket is placed.
- Check the inside and outside transition before final bracket tightening.
The Wire Path Avoids Another Roof Hole
Chris identifies two possible wire routes: cut a separate roof hole, or cut a small corner gouge in the rear passenger-side edge of the gasket area. He chooses the gasket-corner route. That keeps the wire path inside the main AC footprint while avoiding another penetration through the van roof.
This is also where the second person becomes more than a helper. One person manages the heavy unit and alignment from above while the other checks where the cable is landing from below. Before the brackets are fully tightened, some daylight is visible near the cable path; once the brackets pull the unit down, the gap closes.
- Route the cable through the passenger-side rear corner of the gasket area.
- Use the second person to confirm that the wire lands in the intended interior spot.
- Pull the cable down before the bracket compression removes the remaining gap.
- Keep the wire clear of bracket pressure and sharp cut edges.
The 12V Wiring Stays Simple Because the Circuit Was Planned
The electrical work is direct because Chris already has a reserved 12V positive terminal for the AC unit and other 12V loads. The AC positive lead already has a 100A fuse, and he confirms the power is off before making the connection. The cable is zip-tied down the wall and passed through an existing solar input hole, which keeps the install tidy without adding a new route.
Once the system turns on, the control panel wakes up at 68°F, the remote works, the unit light comes on, the swing function moves the vents left and right, and the display reports 12.7V. The lowest selectable temperature is 63°F, which becomes the set point for the cooling test.
- Bring the AC cable from the roof corner down the wall.
- Secure the wire with included zip ties.
- Pass the cable through the existing solar input hole.
- Connect the fused positive lead to the reserved 12V terminal.
- Power the system on only after confirming the circuit is off during wiring.
The Cooling Test Gives Buyers the Numbers They Actually Need
The van begins the test around 85°F inside with intermittent sun and cloud cover. After one hour, the interior is down to 72°F. After another half hour, it reaches 69°F, and Chris realizes turbo had not been running for the whole test.
At the two-hour mark, the interior reaches 61°F, with the AC still running and drawing about 48A. Earlier in the test, while set to 63°F, the system estimates 18 hours of runtime in a large open shell. For a van that is not yet fully finished, those numbers are more useful than a showroom claim because they come from a messy, real build environment.
- Start: 85°F inside the van.
- After 1 hour: 72°F inside.
- After 1.5 hours: 69°F inside, before turbo had been used consistently.
- After 2 hours: 61°F inside with about 48A draw.
- Runtime estimate: 18 hours at a 63°F set point.
The Real Value Is Direct Cooling Without an Overcomplicated Setup
Chris frames the finished install around practical van life rather than a polished shop build. The project includes roof cutting, edge painting, bolt-clearance grinding, gasket trimming, seam pressure, flashing, cable routing, bracket tightening, and direct 12V connection. None of those steps are glamorous, but together they explain why the final cool-down feels earned.
The 11,500 BTU capacity matters because the van is still a large open shell, yet the AC still reaches 61°F in two hours. The 12V architecture matters because Chris can connect it through his DC system without building the install around an inverter-heavy cooling plan. For builders trying to make a hot van livable, that combination of cooling capacity, runtime estimate, and direct-DC wiring is the practical reason this unit stands out.
FAQ
Q: Can this larger AC use a standard fan opening?
A: Chris explains that a standard fan-sized opening can remain, but the surrounding mounting holes still need to be cut. For his roof, he cut a larger 18.1 x 14.1 inch opening because there was no pre-existing fan hole.
