    Does anybody know anything about the floors used in Motorhomes?

    I ask because I want to fit a different table to my 2015 Adria, and need to fix it to the floor. I was going to bolt it through, but there is a chassis member in the way, so I am thinking about self-tappers, or threaded inserts.

    If I drill, and break through the floor I can seal it with mastic where I can get to it, but not where I can’t, for example in the upside-down top-hat section of the chassis.

    So to crystallise my thoughts, does anybody have an idea of the likely thickness (not keen on drilling a test hole), and what material? In a mock up I have found a conventional mate machine screw driven into heavy marine ply more than strong enough, but I fear that even though the loads are light they may be too much for lightweight boards.

    My very last resort would be to bond the base of the table to the floor, or am I wrong to be reluctant to do that?

    Any insight will increase my knowledge 100%, so thanks.

    Why do you need to bolt it to the floor. We have removed ours and I bought a Fammia tripod leg and just attached the table top to that. Which means it is lighter, and I can put it exactly where I want it, including outdoors. If we don't want the table up its easy to store away and you have more room.

    I guess the floor will be composite sandwich. Ali or GRP outer skin, thin ply inner skin and held together with bonded foam insulation. Can't see self tappers or threaded inserts working. Normally drill and bolt through with spreader plate underneath to prevent bolt and washer pulling through the ali/GRP.

    If its already got a table why not see how thats fitted. Mine (Rapido) was just screwed with ordinary woodscrews, so thats how I fixed the smaller replacement.

    It works quite well, Pete. With a drain hole as well, it means that she can 'go' whilst we are 'going', if you see what I mean. :xsmile:

    Not sure this is helping to answer @chuns original post but sure brings it down to floor level if nothing else!

    I think that with a 2015 van that Mikey RV's idea might be the best for several reasons; warranty, you can move it if not quite right and options to use outside.

    Apologies to @Tootles for inconsiderately dragging this thread kicking and screaming back on to topic........

    Sorry to be serious, floor construction is likely to be a sandwich of 2mm ply on either side bonded to either 25 mm or 35mm polystyrene or styrofoam.

    There is really no need to drill the floor to find out how thick it is just measure it.

    It's even easier these days with highly accurate cheap laser levels.

    I think Adria use GRP on the underside. They certainly did with my 2008 coachbuilt.

    Thanks for all the helpful thoughts, and the amusing drift off topic.
