Hi Paul, I'd be happy to help you find the right cover for your Coleman air conditioner. The challenge is that Venture RV used several different Coleman rooftop AC models on the Sonic Lite, so I don't want to guess and recommend the wrong size.

I have listed Coleman AC units with their correct Adco cover below:

Coleman Mini Mach or Super Mach-part # 290-3017
Coleman Mach 15, Mach I Power Saver, Mach III Power Saver, or Mach III Plus- part # 290-3026
Coleman Mach I TSR, Mach II TSR, or Mach III TSR- part # 290-3023

Since you're not sure which Coleman unit you have, just send me the model number from the sticker under the shroud, or a quick photo of the air conditioner, and I'll be happy to help try to identify it for you. That way you'll end up with a cover that fits snugly and helps keep out debris, insects, and the weather. I know it's a pain to climb up on the roof and find the label but it's really the only way.

Where do you usually store your Sonic Lite, in an open driveway, under trees, or somewhere that sees a lot of wind?

I got the dimensions of my Coleman Mach air conditioner is 49"x27"x9" deep. The one I saw was only 37" long. Guide me please. I also want single axle tire covers for st225-75R15 tires. Thx

@PaulB I have a Furrion AC, and this was the only one I could find that was even close in the dimensions.

@PaulB I'd be happy to help! Based on the dimensions you provided, the closest air conditioner cover we carry is the Adco RV Air Conditioner Cover for Coleman Mach TSR ACs - White Part # 290-3023 It measures 43-3/4" long x 29" wide x 14" tall and is designed to fit Coleman Mach I TSR, II TSR, and III TSR air conditioners. That said, I'm not familiar with a Coleman Mach rooftop air conditioner that measures 49 inches long, as most standard Coleman Mach units are typically between 38 and 41 inches in length. If you can provide the model number from the label on your air conditioner, I'd be happy to confirm whether this cover is the correct fit or recommend a better option if needed. For your ST225/75R15 tires, I recommend the SnapRing TireSavers RV Tire Covers - White Part # ST7001WH. These covers are designed to fit tires with an overall diameter of 27 to 29 inches, making them an excellent fit for your tires, which measure approximately 28.3 inches in diameter. They provide great protection against UV rays, dirt, and weather to help prevent dry rot and sidewall cracking during storage. I also like that they use spring-steel snap rings, which make installation quick and easy without having to crawl under the trailer to secure straps or bungee cords.

I ordered both of my covers model specific and they fit perfectly. I just use them over the winter in South Dakota and it’s stored outside. Both covers look great after 4 years use.

Answer 1

We have vinyl covers that would fit your Coleman Mach like the Adco RV AC Unit Cover #290-3026 but we do not carry any covers that are canvas.

Hey Melanie. The reason you can't find a replacement for your GE ARC15AACBL2 15,000 btu air conditioner is because they phased them out. In 2025 all RV AC systems had to change over to a new coolant called R32. This was a EPA mandated decision.…
