She's takin' on water, Cap'n!

Another way is to get some hi intensity illumination (Work lights, flood, halogen etc) and wait until dark at a safe area, home wherever. Have a second person work the lighting on the outside of the sleeper once it gets dark, then you go on up, into the cab and start looking in places you may suspect as to the origin of the leak (s).

Less messy, more effective and a little quicker. If light is seeping in, there's your leak. And don't just stop there, keep searching as it may be more than just one location.

 

you know, this may be redundant, but are all the sleeper windows tightly closed? i had a freighshaker condo, and the upper bunk windows did not fully close, until i locked them. have you checked to make sure of this as well??

 

Hey @Criminey Jade hows the driving er swimming going?

 

actually, with all that water sloshing around, she has a built in Jacuzzi.

 

Mmmmmm

 

ok, just thought i'd bring up the sleeper upper windows.
