Rotten floor

[Gringo]

I had a problem earlier with the lower step being wet through after asking advice I managed to cure it but when I cut it the carpet the wood is completely rotten any body any advice on replacing this it looks as if I remove the fold down step I should be able to effect a repair any advice would be appreciated 1998 autotrail Cheyenne 634

Some photos would be good, so that we can assess the damage and possibly offer guidance.

It may also be worth posting the question on the British motorhomes forum /Auto trail sub forum on this site as someone there may have had this problem and been able to sort it out.
