This is a first for me. Other than O.M.G. how would you respond?

Those appear to be supplemental supports, probably to correct objectionable deflection. One persons objectionable may not be objectionable to another. They may have had a china cabinet that rattled when someone walked across the floor, they might have been very large people, don't know! The thing I look at is; if the supports were not there, would there still be a reportable problem? I would still mention they are in the crawlspace and there condition but might not recommend any action.

Pretty much as Vern said, but a little stronger.
Mostly FYI

If you look carefully pic #2 appears to be a main girth. The joists end on this girth.

Nope.

Nope.

When Jim is correct ... I do agree with him, to the extent that he is correct ... and however seldom that may be ... except that is a girder, not a girth - at least not that I have ever heard.

See zoomed in photo.

We see dry stacked peirs under mobile homes all the time. Works OK.
I agree, posts in pics 1 and 3 were added later.

I would describe the piers with enough pics to make it all clear, what you see is what you get.

Mobile homes are "Well just that" Mobile structures. No need for permanent fixtures. I don't have problems with short dry stacked columns, but if the columns and girt are a permanent solution (like pic#2) then a footing at proper depth and size for location is required.

A) "Mobile homes" are actually not just that, unless you want to think of any home as being "mobile" because they can be moved.

B) Mobile homes are actually "manufactured homes" and are installed on "permanent foundations".

A car is "mobile" ... A "mobile home" would be an RV ... :)

Home is 1600 square feet, single story ranch, on block foundation. Picture #2 does show center girder (double 2 X 12). Girder is centered with 16 foot 2 x 12 floor joists (on 16" centers) running to the back and to the front foundation walls. The girder is supported with dry stacked blocks. The dry stacked blocks are sitting on concrete footers (quality unknown) and two are leaning. The bags of concrete and 6 X 6 posts are positioned between the girder and the front and back wall. Given the girder and joist material used I assumed the 6 X 6 structures to be "floor stiffeners", added by the home owner. Unfortunately the owner died recently so the exact reason is not known. I reported the column construction to be unorthodox and should be considered "temporary" supports only.

Around here the foundation is dry-stacked CMU's under the steel frame.
Preferably on a poured concrete footing. So I guess that concrete slab qualifies for permanent.

Anyway, the stack of blocks can be solidified with rebar and concrete. I would think in Tennessee they can figure out how to get buckets of concrete in there. :)

We can get concrete in Bags.
*why would we need Buckets.;)

I do it occasionally myself, but ... we had just finished making reservations for our next camping trip with our motorhome ("mobile home" :) ) and that target was just too big to miss. :D

Same here, and tied down to ground anchors.

YOU get concrete pad footings? Wow, all WE get are plastic pad footings.

That would require reading the instructions and finding where it says 'mix with water' ... :confused:

We get a few MH's on tippy piers, but with the wheels and axles in place, she won't roll far. [:)]

Ya, everybloody knows that once the dampness does it job..... those bags will be hard as, well, concrete, and the bag will keep it all togeather eh!

The shims leads me to believe this was an after-the -fact installation of the Girth.
