Guarantees

Had my Motorhome for two months now and have a question regarding the Guarantee given by the Dealer I bought it from

I was told that a full service would be given to the van plus a full habitation check would be carried out with a 3 month Guarantee

Now I know that the actual base vehicle, engine etc etc would automatically come with a 6 month mechanical Guarantee meaning that any faults during the first 6 months of ownership will be the responsibility of the Dealer

Does it not follow that the interior is covered by the same 6 month legislation?

Also what degree of damp is considered acceptable? The damp check just carried out is very good apart from readings of 12% over the cab.

Should this be rectified by the Dealer?

The van is an Elddis 105 2015  6k miles Peugeot
