I just this summer replaced my old 2002 trailer with a 33x11.5 park model shingle roof unit.
I removed my porch hardtop roof, I jacked my porch up by about 6 inches, then I put roller skates (actually 6k load car dollies from Amazon) and ripped 1/2 plywood down the middle and made runways for the skates.
The day before unit came in, I rolled the parch with all its walls still attached about 2 feet away from the unit and when it gat installed I rolled it back
