Bolt backing out through siding

[jwoods]

Has anyone seen this before? The head of a bolt is clearly identifiable through the aluminum siding and it seems to be getting worse. This is on a 2012 Jay Flight 28BHS. I have emailed Jayco, but am yet to get a response. I don't have a local Jayco dealer and I'm not comfortable disassembling it to fix. I also have a floor bolt that works its way up through the linoleum flooring on an annual basis, but I can get to that bolt from under the camper and can tighten it back down. This one in the front, I can't get to. If you have a similar experience, I'd be interested in knowing what help Jayco provided and how it was fixed.

Thanks!

Never seen that before. But I'll be watching to see if/when you get a response and eager to hear what they say. Good luck!

Can't help with the front, but I would put thread lock on the bolt in the floor if it keeps loosening up repeatedly. I would assume it has a lock washer on it already.

Just a thought on the front, it MAY be easier to remove an interior wall panel to try and get to it versus removing the exterior siding. ????????

The bolts in the floor appear to be simply self tapping bolts that go through the floor and frame cross members. The bolts stick out about 1" on the bottom. There are no nuts or washers of any kind. I have tried to match the threads and install nuts and lock washers of my own without any luck. To fix in the past, I've simply grabbed it with a vicegrip and turned in back down. At this point the threads are shot on that particular bolt. I'm going to add some JB weld to the threads and hopefully that stops it.

In regard the front, it would seem that is a bolt holding the front bed support, which looks like a 2"X3" piece of wood running cross ways across the front of the camper. I can only see it through the front pass thru storage compartment. My best guess is that its a lag bold and the point is buried in that piece of wood, so I can't get to it.
