Just curious - cold rear bathroom
Bathroom is the coldest place in my trailer. I doubt there is any easy DIY fix for this, just curious why. I know how careless they are at the factory when packing pink insulation wool under aluminum ...

I would expect one factor would be that the rear bathroom to be colder due to the greater wall area compared to floor area. Does it always feel cold or just after getting out of the shower? You will always *feel* colder when getting out of the shower due to evaporative heat loss but having the space warmer is nicer.
The furnace will have a duct or two into the underbelly space to provide the "heated underbelly" feature. Heated air will end up going into the outdoors via gaps in the underbelly to frame. Very inefficient... The furnace circulates air and will require makeup air from somewhere and will therefore draw it from anywhere it can like roof vents, poorly sealed exterior doors, weep holes in windows, etc. Air will also be drawn up from any gaps in the floor for plumbing pipes.
Check under the tub and below the vanity for gaps in the floor and seal with foam or tuck tape. Seal up any other gaps you can find in the floor. I sealed all the openings I could find and some were large. They hacked a big hole in the floor next to the furnace which caused cold/colder air to be sucked back up from the underbelly space which short-circuited the return air grille.
Photo below shows the piece piece I installed next to the furnace. The return air grille is just to the right of the new 4" duct. I also sealed up any gaps in the duct fittings on the furnace with aluminum foil duct tape. The 2" inch duct on top of the furnace goes to the bathroom on the left. This duct originally went under the shower to under the vanity and when I rerouted it, I reduced the duct length by around 8' and greatly improved the flow into the bathroom. Can't see in these photos but the 4" duct to the bedroom is off to the left which I replaced with 2" to better balance flow. Third photo shows the right angle fitting I used at the outlet in the kitchen area (purchased at HVAC wholesaler) - had to enlarge the hole in the floor to make the duct clear the built-in vacuum unit.
