I am having a manufactured home put up in North Texas, in the middle of
a drought.

My site is on the side of a hill, and the mobile home retailer
contracted some guys to dig out the the hill and use that dirt to level
a spot for the home. On one end of the pad, the non-native soil is
about 18"-24" deep. On the other end, almost solid rock.

All they did to pack the soil was to drive over it with a small dozer.

I have no experience in this and asked several people if this will
work, most said it is a bad idea.

So on the suggestion on many, I decided to go pier and beam. All the
pier and beam guys I called will only go down to 18" piers max.

My questions is, if you put 18" piers in soil that isn't packed that
good, am I getting any benefit from the piers, or am I still gonna have
alot of problems?

I think you should drive pilings all the way to
bedrock, on both ends. How far is it to rock,
on the downhill side?

Not disputing what anyone else has said, but remember that you're gonna be
crawling under this thing on a regular basis. I'd put a slab in, if the
concrete truck is gonna be there anyway. If you have pilings or piers taking
the weight, the slab doesn't need to be thick.
