As noted by
@qhumberd in the link below. The basic model MaxxAir fan requires more ceiling thickness than is in the 400 bathroom.
https://tab-rv.vanillacommunity.com/discussion/10700/bathroom-fan-replacementI found that MaxxAir offers the Maxxfan Low Profile, that has the basic features of the base fan (4 speeds), but can be installed in 1" thick ceilings. It's available at etrailer.com.

BTW we love our slightly bulgy version of this fan and use it with the bathroom door propped for ventilation as it is so quiet.
