Damp seating area
I need a bit of advice other than going straight to my caravan supplier.
i have a Lunar Clubman SI 2014 which has mysteriously developed a damp area over the heating mechanism Onto the seats.
The unit has been back into the supplier where no leaks were found so we dried the foam seating and it's covers against radiators in house for 3/4 days.This dried everything off but as soon as we put the seating back into the unit (on the bed) within a couple
of days they were just about wet again...cannot understand...

I have read of some foam being hygroscopic. It could be due to that. Was the surface dry before you put the cushions back? Do they get as damp if you leave them in, say, the garage?
If the dampness is not coming from the air, it must be coming from somewhere else. Has your heating system lost any fluid? Try placing some coloured tissue paper (that goes darker when wet) in the area that’s getting damp. It may help to indicate if anything
is dripping onto it.0 -
I assume like ours your caravan has the heater under the front offside seat in the front lounge. I can see no way that liquid from this can get up onto the seat and if it was water there would be some sign of it on the wooden slats under the cushion. I would
keep the cushion off and check the seat base. You could try swapping the cushion from the other side and see if that gets damp, if not then it is a problem with the damp cushion, if the other gets damp it can only be the caravan. I do wonder if the water
tank under there is drained as if not it could be attracting condensation and it needs draining urgently.0 -
It seems unlikely that the damp us coming up from below. As rougher says perhaps there is a leak from above. I would suggest placing a co.oued paper towel over the damp area as previously said to see if there are any drips from above. Is there a roof light
above where the dampness is present on the bed?0 -
Like others have said using coloured absobent paper is a good idea. I have rolls of the blue paper often sold for decorating puposes or as hand towels in the work place. It realy does show if there is any damp about. I use it after plumbing jobs to check
for leaks. If you can get some, then wipe the ceiling above the affected area, if there is a drip it could be running sideways before it falls. Good luck.0 -
Morning guys sorry for the delay in replying went to bed early..big day today
well just been in the unit to check..left the cushions on the bed for 3 days and again it's really damp so bringing it in to dry it out. think I'll remove the cushion covers and see what happens when I leave it in the spare bedroom...if not I'll find out
what the warranty suggestsbut I think the foam may be doing it cheers

Damp caused by condensation has been a topic on motorhome forums recently. The exceptionally damp weather is not helping. Common causes have been change to memory foam mattresses without improving airflow, inappropriate mattreses supplied by manufactturers,
quality of bedding used, lack of air gaps around mattresses, and blocked ventilation holes in the van limiting overall air circulation. There seems to be a specific issue with some mattresses from one manufacturer [these are being replaced under warranty].
There is also an issue in some motorohomes with the fitting of Truma boilers in that the airflow is not as specificed by Truma - not a problem unless you are using a Truma boiler.I assume Lunar has an owners club so it would be worth checking its forum to see whether there is a known problem.
