when my roof ac on the rv died in July, in Florida, this unit saved the day...literally. this unit cools/heats a 30 ft RV, takes up very little floor space, is pretty darn quiet (and I am closed in, do not have to add volume to the tv). it cut my power bill by 30 percent. it rolls easily. is easy to install. even with RV windows it fit in the space I needed it to. the cons: it has modes. you can't just switch from heat to cool without powering through all the modes. I hate modes. the blue backlight does not light up the panel to see the icons, and the overflow tray for draining is small and when in heat mode it has to be emptied nearly every hour as the unit shuts off when the tray is full. even when empty at bedtime it has to be emptied at least twice overnight. it does come with a long drain hose, that I haven't figured out yet. I would definitely recommend this product.
