Ed Pawlowski was heard to mutter:

The only sure way to eliminate transition is to use the same material
throughout. Even then you may have 1/16" Or spray the floor with self

House came with all carpet and vinyl sheet. Baths, hallway and kitchen
were vinyl. Rest carpet. Dinning was carpet over vinyl sheet because
entire roll goes across one half of the double wide. All stapled down;
under cabinets and walls too.

Our trash pickup company will not take carpet, tile, etc,.

Sure they will, but it becomes a long term project to put the pieces in
the can every week.

Uh no. Can't store anything outside and no place to store it inside.
Not allowed to store outside. Communities don't allow 'eyesores'.
