    Hi
    I need to fix a bracket on the back of my Knaus to support a frame off the tow bar frame,
    to stop it swaying, is the whole rear end timber underneath the finish coat
    Hope that makes sense

    No it wont be. It will be a sandwich of thin ply inside skin GRP outside skin with high density foam between. You'll need something like a Fiamma bike rack mounting that goes right through the wall (where it wont be on view)
    Typical construction used in most modern vans.

    Some manufacturers incorporate spot reinforcements within the sandwich but you'd best contact them via their customer support for these specifics.

    The problem with a foam sandwich construction is that it is compressible if you bolt right though without a through solid spacer then the foam will collapse when movement is applied to it so you end up with a loose and leaking joint. flexing of the rear wall can cause delamination and leakage around any openings in the rear wall as well as gelcoat fractures eventually leading to osmosis. It really is not a DIY job. If done by a manufacturer then any subsequent problems are down to them to rectify.

    High density foam needs a lot of pressure to compress it, this is achieved by over zealous use of spanners. :Laughing:
