....yup, some HP units can be noisy, depending on ducting, but easy to work around. We have two units--one front, one back. When we are up front, we use the back unit; when we are in the bedroom, we use the front one. When weather is changeable, we set one on A/C for daytime use, and one on heat for night time --works great!!!! As for annoying fellow campers--really???????
