you could avoid wasteing electricity by not sending the bleeding obviouse on your computer , dave

Start taking your pills socket. If it's obvious (there is a spelling checker here) why ask at all?

I made constructive suggestions, but I was taking a humorous angle on how damned hard to stop condensation it is, entirely esp on cold and windy nights..

As well as what runs down into the base, you're probably getting the condensation from the proximity to the cold metal of the roof rack. Try some insulation either under the tent or under the mattress - you can get polystyrene with a coating on it... you could try that too.

Hahahahahaha

g,day eric , yes it is the underside, the roofrack side. i understand how it happens ,with warmth inside & the cold air outside between roof & tent base, but it is a pain to remove mattress to dry every day , hope you have an idea , thanks dave.

I think you will find its body perspiration from you and partner going through the foam mattress. If its a cotton covered foam.
Just A thought.

All the best
Eric
