Install permanent foundation under existing mobile home

[Tracy J. Adkins]

Has anyone found any foundation systems that can be installed without having to move a doublewide thats been in place for a decade or two? 

I know that can pull the house out of the way and do a traditional slab/pit, but was curious if there was a better way. The idea is to be able to get the house into FHA standards, ie strapped down to a permanent foundation.

Thanks all

I haven't done this, but I work in the construction industry and I think it would be very easy to build a foundation to a height, just below the frame, and then jack the home down to transfer the load to the new foundation.  I would leave an opening through the new foundation for access and then close it up at the end.  

You may want to talk to a local home mover.  Those guys deal with all sorts of weird things and can be a great resource.  They own jacking and blocking equipment too.  So maybe they'll even give you a quote.
