Not all mobil homes are built the same so it's hard to say exactly what your going to run into.
Some lovly things I ran into with them.
Sheathing on the roof that was only 3/8 thick.
Just kraft paper instead of tar paper as a vaper barrier on the roof.
Shingles were staped not nailed.
They used staples to attach the vinyl siding which will cause it to buckle.
Doors inside and out non standard sizes.
Quest plumbing which years ago had all kinds of class action sutes from pipes bursting and fitting leaking.
Partical board floors which if they get wet one time turn to oatmeal.
Cheap windows.
2 X 2's for wall studs instead of 2 X 4's.
Cheap plastic faucets.
I've seen where they used nothing but plaster rings to hold in the outlet. Pull on the outlet to remove a plug and the whole outlet come out of the wall.
Partical board cabinet drawers and partical board cabinet doors that tend to fall apart and the hindge screws pull out.
Dryer vent and condinsate drain just run under the home, not to the outside.
Thank goodness there not all built like this.
