I have owned two RV's and I have three generators currently. One Honda is loud as **** and it is used for job site work or for the house in times that tornados hit it. My 2k watt generator is portable and quieter than most. The 40+ year old genset in my current RV is fairly quiet, just not to todays standards. Not overly loud inside the coach itself.
As to sleeping in a pool of semen. I think I could figure that out. Having traces of it on your faucet, light switches or phone, thats another story. I dated a girl that worked at a nice hotel and I assure you, semen, poop and snot land everywhere. Please, please, please bring a good quality black light and take pictures of your next hotel stay. I'd love to see how clean the room is. Don't be surprised when your pillow and light switches look like this. And don't lick your fingers once you've taken the pictures, even though we know you want to.
