I installed one in my fifth wheel. Pretty easy install- need to be able to screw it down + get access to the canister to empty the bags. Then it's the hose + a lightweight connector to somewhere inside to plug it in at.
It's not a great vacuum but it's very convenient. We hang the hard hoses in the bathroom with our Swiffer and broom. And I bought a vacuum hose holder
from IKEA and hung that inside of a cabinet.
We have friends who have one and then later bought a Dyson. The Dyson outcleaned the central vac by a lot. BUT, theirs is bulky and lives in their living room.
