Daniel, the Dometic units like # DMC74MR (doorless, no service door for outside the rv) are about on par with late-model Atwoods in terms of fan noise. You’ll definitely hear the blower kick in, but many folks say the tone is smoother, less “rattly” than older furnaces, especially if your old one has a few miles on her. It also has a built-in soft start capacitor so that it pulls less amps at first and has a less noisy startup. So I'd confidently say it will be less noisy than an older Atwood model.

The ducting setup also makes a big difference - longer runs can muffle noise, while short direct vents can be louder.
Are you mostly concerned about bedroom noise? Or the area you are installing the furnace?

Other readers - what’s been your noise experience with these?

Also, keep in mind, this furnace is also available with white service door in kit # DMC99MR or black service door in kit # DMC64MR.
