I think I mentioned earlier that my son has drafted me to help build a fair
ly large deck at his cabin. The cabin is a manufactured home elevated abou
t two feet over a concrete slab. There is skirting running around the peri
meter of the structure. The skirting is framed in 2x4s with verticle studs
16 inches on center.
So ... here's the question: can we attach the ledger board to the skirting
framework? Or is a better approach a free-standing deck?
Well, you *could* attach the ledger to that "knee wall" and it might
hold up for decades, but you're taking a big chance.
Is there a foundation under that slab, directly beneath that skirting,
or is the home being supported somewhere else, like a trailer frame? If
there are footings under that slab that act as the foundation of this
home, then you're good.
If the slab is just a 4" floater, then it could easily crack and fail from
the weight of the deck, depending on how large it is. I would recommend
a separate deck foundation-- post and beam. Set the piers 2 to 3 feet
away from the home and cantilever the deck joists towards the home,
leaving a decent gap for water to pass between the decking and the home
without getting trapped.
"Playing is not something I do at night, it's my function in life"
" Free-Standing " means ... on-ground deck blocks ?
.. or concrete piers going down 3 - 4 feet deep .. ?
Timely post - I'm needing to re-build my 12 x 20 deck -
after it failed last summer - the "anchors" started to fail -
where they were connected into the house . .
< might have been just nails ? dunno yet >
... what a pain-in-the-butt !
I've added a small dog-run around half the deck ..
I'm thinking of pressure-treated framework -
with, perhaps - synthetic decking ?
Any helpful advice / experience - is appreciated.

Sonotubes 3-4 feet down with saddles for the front porch. The rear
deck just had 8 inch postholes dug, 4x4 cedat posts stuck in, framing
set into the posts and nailed, holes back-filled with fast setting
sacrete, tamped and watered. The holes are about 2 1/2 feet deep in
sandy gravel base - very well drained. The deck framing was done
before I bought the house 33 years ago, and when I rebuilt the deck
about 20 years ago I was able to pull the old cedar posts out of the
concrete and drive new ones back in on all but one of the 10 holes. I
had to remove the broken concrete from one hole and re-fill it. I used
pressure treated SYP instead of cedar when I rebuilt it.
The skirting framing is built specifically to hold the skirting. Not a
tough job for the framing.
In so much that it was not designed to hold a heavy deck too I think I
would go free standing and cantilever over to close the gap.

The last thing we need on the ole interweb is redundant information. It would start to get really messy. ;-)
I vote for a free standing deck.
Manufactured/mobile homes are typically supported by a steel frame running
down the middle of the home. They do not have the structural rim joists
around the perimeter like a traditional home.
When we had our mobile home I built two free standing decks. I just used
deck blocks sitting on the ground, and framed the deck structure so there
was about a one inch gap between the deck and mobile. This allowed each to
move independently, as well as letting water/snow run off without causing
rot. When we sold the mobile and moved it out, I simply tore down the decks
leaving no damage to the mobile itself. Both decks lasted 13 years in use,
then I recycled the redwood to build a bookcase and a variety of shelves.
Remember to add diagonal bracing to your deck structure. Since it won't be
secured to the house, you need to prevent it from wracking side to side.
Thanks, guys. Free-standing it is. Now ... if anyone is in the neighborho
od of Wausaukee, WI, next month we've got a lot of cold ones in the fridge
in exchange for a little deck building.
