The dreaded "L" word.  Its the rainy season and the LQ area of my trailer is leaking.  It may sound strange, but it appears to be coming in through the AC and down through the paneling and comes out the bottom of the panel between the fridge... 

 I was able to cover the AC with a tarp last night in the pouring rain and am bringing a ladder out, some help, new tarp, towels, etc.  I'm hoping we just need to recaulk around the AC/roof - anything else we should look for?  

I am so bummed....

There is a gasket around the AC unit where it sits on the hole in your roof.  There are a couple of bolts that can be tightened from inside the trailer, you have to drop the interior AC cover.  These bolts secure the unit snugly against that seal.  This happened to us in a motorhome and that 15 minute fix has kept it perfect for 3 years since the initial inicident.  Good luck with yours...

So all my clearance lites have a bead of silicone across the top and down the sides. I left the bottoms un-caulked to allow drainage should anything get behind the lites.

So far, so good.

We got up on the roof last night.  There is a thick row of some type of caulking covering where the roof meets the walls.  It appears to have some cracks in it and we think that is where the water is leaking down inside the trailer.    It's a Shadow trailer, so I'm calling the dealer today to see what they recommend.

Is it better to remove all the old caulking/silicone and replace with new or just add to it.  And what is the best product to use.

It's an '03 and the hot Fla sun just bakes on it all the time as I don't have access to any type of shelter, so it might be something I'll need to redo every few years.  We figure on redoing the whole top to make sure its all sealed.

 For now we covered the LQ area and into the horse area with a huge tarp, tied it all down, etc so it won't get any more water on it and we'll work on it Sunday.

just spoke to a good friend that owns a Paint supply company (Devoe paint).  They have a product called hydroderm that stops leaks.  He said to paint on 1-2 coats and let it dry, then paint over it with aluminum enamel paint as it will stay tacky otherwise.   He says he sells tons of it to roofers and they all swear by the stuff.

We've used this on many of the City buildings (where I work) to stop leaks and it's fantastic stuff.  I'll let ya'll know how it works out.
