The 5K window unit I have is so so quiet especially compared to a 13.5 RV unit..Something like 48db if I remember right..And yes to the sleeved units..Why couldn't they do the same for a TC?
Some have said a 5K didn't or wouldn't keep there large TC cool..I su-pose it depends on the unit,mine blows ice cold air and it's 5 years old but mine is a 9.6ft non-slide TC and at 102 degree's last week,my Victron sence said the battery area was 70 degree's even in a cupboard with the door open..
Many have modded there TC for a window unit out the back but I just put it out the side window as needed,At 39 pounds,it's easy..A factory sleeved one would be really nice or a professional install,the same..I don't have the skills anymore to tackle that but I have a few bucks set aside for a cabinet carpenter to do in is slow time..
My 8K window AC is fairly loud compared but still way quieter than an RV AC..Ihad a roof unit in my last Lance and that was loud,really loud and it was a new one..
