Furion is a division of Lipert, or LCI --- they make just about every component used in a modern RV today. When you buy a Keystone, Grand Design, or any of the 'big' names you are basically buying a "kit" of pieces made by lippert. They make axles, brakes, frames, steps, fridges, freezer, Air Conditioner and any other component that they need.
This includes of course air conditioenrs, and mechanisms for slide-out rooms. Slim Rack is one of the variants they make, also Schwintech which is a similar system....a quick google search will return results. In diagnosing problems with any of these systems, the basic rule is you need to check 3 things....The sensor or motor, the harness, and the controller for it. Unofficailly, there is a 4'th step "hope and pray" as the slide-outs are notoriously unreliable.
I'm in a class this week (continuing education) which deals with Slides, Air Conditioners, Hydraulic systems (leveling gear), refrigerators, and water heaters. 3 days of lecture and hands-on. Pretty decent, but reminding me why every day I love my campinn more and more. Reasons? Refrigerators that have a room temperature probe that is wired through the body of the refrigerator. If this little $5 sensor fails, you have to buy a new refrigerator...you can't fix it. Or a door seal, just like on your home refrigerator --- when it fails, you have to buy a whole new door.
These guys are unethical. Pure and simple. No wonder elkharts is 'dying' right now as people who bought campers in 2020 are regretting it, and selling on the used market in droves.
There's a huge problem here, that we are fortunate enough not to have to worry about.
I DID break down and take a shower this morning. Florida at least puts heavy duty fans in that move the humid air out --- here in Indiana, not so much --- just leaving windows open. 100% humidity and warm even first thing in the morning. THIS is the one thing I do miss about owning a full-size camper. shower and bathroom. Something to be said for it. But thats the only thing I truly "miss"
