We took the metal roof off of our mobile to put a pitched roof on. We had a General/84 so I don't know your home.
The one thing I wanted to caution you on is that there is insulation under there and if you aren't careful where you walk, you go right through the ceiling into the house.
That is a disaster to fix!
We built the roof trusses ourselves to save money and "Hubby",brother and friend made roof tight in a weekend.
With the new siding added our 84' looked like a brand new home on the outside.
