   Its really hard ot say without LOTS more details. But one area that comes quickly to mind is the point at which the new and old roofs are joined.

    

    

   Unless you're the lead dog, the view just never changes.

   You might add in what sort of climate you live in and what sort of soils you are living on, the type of foundation you plan to build, and what the mobile sits on now.

   You can do it, but it may not always be what you'd hoped for.

   Gravel,gravel,and more gravel.The whole thing is on gravel that was trucked in 10-15years ago. The mobile home is on solid blocks every 4-5ft. supporting the frame rails. Town water with private septic system,there's been no problems with pipes under the home,or any sign of lifting with frost. We are in cenrtal Massachusetts, I think with the dry gravel base there's no frost heaving. Addition roof is 90degrees to the home roof with a valley and then running with it and over the porch roof to the end of the porch. New rafters added from outside wall of porch to the peak of the home with a short wall at mid span being the outside home wall. Metal roof over all of it.

   Where I live it's required that mobiles be set on a "strip footing". It's not under the perimeter. It's under the support beams, must be mono poured with rebar, and the metal mobile frame must be welded to the footing (usually with rebar, sometimes with log chain).No one can tell you ABSOLUTELY whether or not there will be different movement between old and new. If it was me, I'd probably just go for it.Best of luck to you.++++++++++++++++++++++++++++++++++++++++++++++++++

   You are right about the gravel preventing frost heave. If you're on gravel like you say, I wouldn't worry about the old "floating" away from the new. But, I am not an engineer.

   Last time I did this, I extended the basement under the mobile home to the frame rails, and replaced that section of piers with an 8" CMU wall on a strip footing contiguous with the rest of the addition.
