i have a 1995 fleetwood
?somedays i come out and my front floors under the mats are
very damp-'not wet'
does anyone know what causes this!

 

does it smell of anti-freeze? or do you have to fill your radiator often. your heater core may have a small leak

 

If you do not smell antifreeze then check door seals by shuting door on a pieace of paper and pull the paper,if easy to pull out,might be coming in.I had an Olds Aurora tha had water in floor and had to repair the seal.If have a sunroof check for stopped up drain hoses.Have a great day.David
