First, I'll take photos of mine later today.
I doubt if the problem is the door to door frame weatherstrip. I am currently working on my project Fiber Stream
, and I can see daylight in places between the door and door frame. We have had some major storms in the past weeks, and no wet spots in the trailer.
If the leakage is occurring when the trailer is stationary, the likely culprit is the caulking between the door frame and the trailer fiberglass wall. You MAY
be able to get a short term fix using something like silicone, but the only real solution is to remove the door, then remove the door frame, and re-caulk using the butyl caulk tape spoken of in other posts.
A more distant possibility is the rain awning
over the door. Have a close look at the top of it; is it bent away from the trailer wall, or is it missing screws. The fix here is as above.
If the leakage does not occur when the trailer is stationary, but shows up after towing in the rain, there is another possiblity. The door is directlly behind the rear axle
wheel. The trailer floor extends to within an inch of this rear wheel. All my aluminum sheeting has badly deteriorated over the bottom of the trailer, especially in this location. Also, in my Fiber Stream
, the floor carriage bolts attaching the trailer to the frame are all loose. As a result, in places, the floor has broken away from the trailer shell, including at the entry door.
My solution is rather extensive:
Remove all accessible aluminum floor sheathing (Mine tore away easily by hand, only had to use a utility knife in the areas that the sheeting overlapped).
Replace floor-to-frame carriage bolts with elevator bolts. Due to head size and bolt hole spacing, I will leave a few of the old bolts tightened in place, and install new belevator bolts nearby.
Fiberglass (resin and chopped mat) the entire inside floor (the floor is actually invery good condition, but was wet when I removed the carpet).
Undercoat the trailer</blockquote>
Photos to follow, hope this helps.
