Our Wolf Creek didn’t come with an air conditioner when we bought it, yet that was fine with us. We wanted to choose our own unit. What we were looking for was simple. We wanted a low profile unit that could keep our camper cool while plugged into a Honda EU2000i portable generator. With those requirements in mind the choice was pretty easy: the Coleman Mach-8 Polar Cub 9200.
We love our little Polar Cub. Only 10 inches high, the low profile exterior of the Polar Cub not only looks great on top of the camper, but it also creates less wind resistance on the road. In our opinion, few things are uglier on an RV than a big, bulky air conditioner on the roof. But the benefits of owning a Polar Cub go far beyond looks and wind drag. The diminutive unit weighs only 96 pounds, a good 30 to 40 pounds lighter than the leading 13,500 BTU air conditioners. That weight may not seem like much, but with pickup truck GVWRs and payloads being limited like they are, every pound counts, especially if you own a half-ton or 3/4-ton truck. Advertised features of the Mach 8 Polar Cub 9200 air conditioner include:
- Highest Air Flow Delivery On High Speed, And Ultra Quiet On Low Speed For Night Time Cooling
- Molded One Piece Fiberglass Base Pan Provides Excellent Durability With Reduced Weight
- Lower Profile Means Less Drag And Improved Fuel Efficiency
- Delivers The Same High BTUs Of Cooling On Both High And Low Speed Operation
- Operates Even At Desert Conditions Of 125 Degrees Fahrenheit
- Has The Largest BTU Resistance Heater Of Any RV Air Conditioner
- Installs Easily From The Roof For Ducted Top Down Mounted Systems
- Limited 2 Year Manufacturer Warranty
Perhaps the biggest advantage of owning a Polar Cub is its small power requirement. On its highest setting, the Polar Cub requires only 11.7 amps AC to run. Our little Honda EU2000i generator, capable of generating 13.3 amps, does the job with ease and we can even run the Polar Cub with our camper plugged into a regular 110 volt, 15 amp household outlet. You may be wondering, “yeah, but can the Polar Cub keep your camper cool in extreme heat?” That’s a great question! We’ve used our Polar Cub in 112 degree temperatures here in the Arizona summers and it never fails to keep our camper nice and cool. We’ve found the bullet point above regarding the 125-degree capability to be spot on.
I’m pretty handy, but I’ve never installed a roof top air conditioner and probably never will. The units are simply too heavy and bulky to heft up on the roof. The risk for injury or damage to the unit is too great. This task is best left to RV service centers who have electric lifts to hoist these puppies up on the roof. It’s money well spent.
