I have a 2011 Heartland Northtrail. I noticed recently that moisture is coming into the cargo area on the front of the trailer. Entering around the cargo light fixture that is inside the cargo space on the front wall and where the floor of the space meets the front wall.
My question is; I have a rockguard on the trailer (see picture) and I was wondering if there is a seam between the rockguard and front panel or is the rockguard applied on top of the fiberglass?
If there is not a seam, the only thing I can think of is that the water may be entering along the seam between the front panel and the side panel? Or at the at the top of the front panel where the panel meets the roof. Could water enter at that seam and travel down through the wall all the way to the bottom?
I took out a window one time to re-caulk and noticed that the wall is filed with styrofoam. Does the styrofoam allow water to migrate down through it?
Also, can someone tell me the name of the metal / plastic joiner that they joined the corners of the trailer together with? I would like to know how it is made and whether I can remove it to look for a leak
Do you have any suggestions?
Are there marker lights at the top of the panel. The majority of the leaks I have encountered have been front marker lights.
Not very often will you get a leak at the seams. You always need to check the self levelling caulking on your roof, then check the lights. I would remove them, look into the hole where the wire goes and see if you can spot signs of moister. My buddy just pulled his front window out thinking it was leaking. He brought it over to my how and we ran a hose over it and found after an hour the water showed backup. Pulled the marker lights, and found pools of standing water. Just siliconed them back on, and the screws.
I hope this helps. Good luck.
