I have a 30 year old mobile home with a bay window. The bay window is
sagging now and we're going to yank it out. What I would like to do is
actually extend the floor the 22 inches out to gain a bit of space.
The floor joists in the mobile home run vertically down the length of the
trailer, so what I was thinking was just to take 8 foot 2x6s and sister them
on to the existing floor joists, with six feet joined to the existing joists
and then about 2 feet (well, 22 inches) hanging suspended.
What I want to know is whether this is a viable solution. Some people I've
talked to say that I should really be pouring a proper concrete footing if I
want to extend out past the frame of the trailer, while others think that
what I've come up with, if using proper hangers and bolts, should be more
than enough to support the floor above.
