Mobile Home Plumbing inside vs under the MH

Mobile homes plumbing usually runs under the mobile home beside the heat vent runs. Well the previous owners took out the furnace and we removed the nasty painted cardboard vents when all of the floors were replaced.  If you have an older MH --ours was 1973-- I highly recommend getting new duct work if you have a furnace, replace with metal or the insulated flex tube. Both MH's duct work was open at both ends where it had become un-stapled so it was heating/ac under the MH not the MH,  plus the things that had made homes in it...
OK back to plumbing... we ran the main water line into the MH then ran all of the plumbing inside the home. We did this for many reasons. Easy maintenance--we live 3 hours away. Sometimes in a MH you do not know you have a water leek until you get the high water bill. Finding the leek involves crawling under the MH and opening up the material /insulation until you find the leek. Not with the lines run inside the MH.  Our daughter was living their and she could fix a leak with just a few basic supplies. Winter--no frozen lines.  Plus if we want to add to the plumbing it will be easy to do. In the photos you can see the plumbing lines especially in the bath but this will be boxed in with a cover or we are building custom storage areas. In the kitchen we built a corner cabinet that covers all that you see in the photos.
