    Hi all,looking for a bit of advice before i start work to repair my m/h.Its a2006 ci644.I was poking around underneath and came across a soft spot on the floor in the nearside rear corner about two feet in from the rear.gave it a nudge with a screwdriver and the ply came away exposing the polystyrene insulation,is it possible that it could be from spray from back wheels causing the problem or should i be stripping out the shower which is above that area.The polystyrene didnt appear to be wet when the wood came away.Also the timber that runs along the rear which holds the back valance is rotten in both corners.....i suspect water been constantly running on to it from poor sealing at back valance.
    You have probably heard all this too many times before so i thought id ask before i start stripping anything.Any input would be gratefull.Thanks John

    Usually photos can help and say a 1000 words. It might give the knowledgeable folk a better idea of your problem. :)

    More likely the shower is leaking than the underfloor is rotting from the outside.
    You will probably find the rear walls are also rotting.
    Big job for a diy-er to undertake.

    had it before on to motorhomes both corners its water from back wheels running along and ending
    at corners I let it dry then carfully removed rotten wood as it is only couple of mm thick I just put over sized wood over a bigger area and sealed it

    very common faults which if caught early enough shouldn't lead to too many tears. remove rotten wood and test the structural frame for moisture with a meter. if nearly dry, seal the rear valance but give the floor a week or more to dry out before reboarding and sealing well. if it's really wet, trace it back to the source. showers are frequent culprits as they leak round the edges and often crack near the waste or on unsupported areas. if it is the shower that has leaked, expect a big job, as all rotten wood must be replaced

    good luck with it as its a tough job but very satisfying to complete for somebody with good diy skills

    Hi..thanks for tbe
    advice...I think my next step will be to remove the rear light valance and side valances and have a look.......thinking ill see if timber across rear an be repla ed with aluminium channel or box section.as for the floor im going to cut bad section out from u
    derneath and have a better look at the insulation and see if its damp.

    Hi all.I was having another look at the van today and in particular the rear valance and side skirts.The rear valance appears to be sealed pretty poorly and in fact is not sealed in the corners at all which is where I think the problem stems from.Ive taken some pics of the damaged area underneath and will try to add them to this post although this modern technology bamboozles me half the ti 20151101_093317.jpg 20151101_093317.jpg 20151101_093224.jpg 20151101_093122.jpg 20151101_093130.jpg me:-(
