It drops into a standard 14.25 inch roof opening, runs ducted or non-ducted from the same unit, and its inverter compressor ramps up and down instead of slamming on and off. Black powder-coated shroud, 68 pounds, 115 volt.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Coleman-Mach Everest VS-18 is Coleman's variable-speed rooftop air conditioner, built to pull down the temperature in a big rig on a hot afternoon and then hold it there without much fuss. It puts out a full 18,000 BTU of cooling, which is about as much as you'll get from a single rooftop unit. So it's the one you reach for when you've got a large travel trailer, a fifth wheel, or a Class A motorhome and a smaller AC just can't keep up in July.\u003c\/p\u003e\n\u003cp\u003eThe thing that sets the Everest apart from a standard RV air conditioner is the variable-speed inverter compressor. A regular rooftop unit only knows two settings, full blast or off, so it slams on, overcools, shuts down, and then kicks back on a few minutes later. The Everest ramps its output up and down to match how hard the coach is actually working. Once the cabin hits your set temperature, it eases off and just sips power to hold the line. That means quieter running, fewer of those jarring on-off cycles, and a more even temperature end to end.\u003c\/p\u003e\n\u003cp\u003eIt's also a lot friendlier to your power. The Everest has an integrated soft-start built in, so it doesn't hit your generator or shore pedestal with a big surge every time the compressor spins up. Anyone who's tripped a breaker or watched the lights dim when the AC kicks on knows exactly why that matters. The soft ramp keeps startup draw down, which makes this unit a good match for generator-powered dry camping and for parks with touchy 30-amp service.\u003c\/p\u003e\n\u003cp\u003eAirflow is handled by a 360 degree distribution design pushing up to 270 CFM. Cold air spreads out across the coach instead of dumping straight down under the unit. And here's the flexible part: the same VS-18 runs ducted or non-ducted, so you don't have to order a different model depending on your roof. If your rig has ductwork in the ceiling, it feeds the ducts. If it doesn't, you run it through a non-ducted ceiling assembly and cool a single open space. One unit covers both setups.\u003c\/p\u003e\n\u003cp\u003eOn the install side, the Everest drops into a standard 14.25 inch by 14.25 inch roof opening, the same cutout most RV rooftop units use, so it's a straight swap on a lot of coaches. The base pan is powder-coated steel to stand up to sun, rain, and road grime year after year. The shroud is black. Just know it's a 68 pound unit going up on a roof, so plan on two people and a solid, safe way to get it up there. This isn't a one-person job.\u003c\/p\u003e\n\u003cp\u003eOne important thing to sort out before you order: the VS-18 is the rooftop unit only. The ceiling assembly (part 2111-0044) and the digital thermostat (part 2111-0043) are sold separately, and you need both to finish the job. A lot of folks miss that and end up waiting on parts mid-install. So if this is a fresh setup rather than a straight replacement, add the matching ceiling assembly and thermostat to your order up front and save yourself the delay.\u003c\/p\u003e\n\u003cp\u003eWho's it for? If you camp in real heat, run a bigger coach, or you're just tired of the constant on-off racket from an old rooftop unit, the variable-speed Everest is a clear step up. If you only camp in mild weather or you've got a small teardrop, you're probably paying for capacity and features you won't lean on. And one more note: this is a cooling air conditioner, not a heat pump, so it won't warm the coach on cold mornings. For heat you'll still lean on your furnace. But for knocking down the heat on a scorcher and keeping it comfortable overnight, the VS-18 does the job and does it quietly.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e18,000 BTU of cooling, about the most a single rooftop RV unit puts out, sized for large trailers, fifth wheels, and Class A motorhomes\u003c\/li\u003e\n  \u003cli\u003eVariable-speed inverter compressor ramps output to the load instead of cycling full-on and off, for quieter, steadier cooling\u003c\/li\u003e\n  \u003cli\u003eIntegrated soft-start keeps the startup surge down so it's easier on generators and 30-amp shore power\u003c\/li\u003e\n  \u003cli\u003e270 CFM airflow with 360 degree distribution spreads cold air across the coach instead of dumping it straight down\u003c\/li\u003e\n  \u003cli\u003eRuns ducted or non-ducted from the same unit, no separate model to choose\u003c\/li\u003e\n  \u003cli\u003eFits a standard 14.25 in x 14.25 in roof opening for a straight swap on most coaches\u003c\/li\u003e\n  \u003cli\u003ePowder-coated steel base pan stands up to sun, rain, and road grime\u003c\/li\u003e\n  \u003cli\u003eBlack shroud finish\u003c\/li\u003e\n  \u003cli\u003eRuns on standard 115 volt RV power\u003c\/li\u003e\n  \u003cli\u003e68 pound rooftop unit, dimensions 32.5 in x 25.1 in x 12.6 in\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized COLEMAN RVP reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat size RV will an 18,000 BTU air conditioner cool?\u003c\/summary\u003e\n    \u003cp\u003e18,000 BTU is about as much cooling as a single rooftop unit puts out, so it's suited to larger rigs: big travel trailers, fifth wheels, and Class A motorhomes.
