So I finished my camper over a year ago, and have spent six months on the road living out of it while I moved across the country. I absolutely love it, but have had consistent issues with leaks both around the doors and the mushroom vents. In regards to the doors, I think it’s a tough issue to fix just because the nature of how my doors ended up fitting together. The top and bottom edge of the doors aren’t flush with the camper, and I think this is where the water leaks in. I find after a good rain the foam strips on the inside of the door are completely saturated with water and start to leak out onto my mattress. I’ve tried tightening the tension strap on the inside, but it hasn’t helped. Anyone else dealing with this/have any solutions?
In regards to the mushroom vents, I’m sort of baffled. I did everything exactly right, and as far as I can tell they are exactly how they were intended to be. Yet they consistently leak water through them even when they are closed. Anyone have a clue what is going on here?
I don’t have any suggestions about the door leaks, but what I did with the mushroom vents was to put a strip of Frost King foam inside the cap so when the cap is snugged down the foam seals against the inner part of the vent. haven’t had any water intrusion.
Both front and back I installed the base plate on the outside not the inside as per manual. In the front to compensate for the curved surface I used nylon shims/spacers from my neighborhood hardware store to have a flat surface for the vent to mate with. Then calked in the gaps. In the front I drilled a small weep hole (3/32?) at the base just in front of the bug screen. I also sealed the bug screen up about an inch with Marine Goo (Shoe Goo). In the rear the vent sloops down so no weep hole or Goo. Results, no leaks, no foam used.
Also note I use longer bolts and some handles so the vents can be opened and close from the inside.
