Finding Studs Behind Exterior Aluminum Siding

Go out early in the morning and look for the dew lines.

I have heard of that method but my trailer is not being used and stored under cover so you don't get those temperature changes...

Move it outdoors.

You might be able to hear the difference when you tap along the wall. Works on the house when looking for studs, hopefully works on the rig.

Knuckle knock method.

Haven't tried it but how about splashing hot water in the area you want to find the stud. Would it be possible to move the rig out from under the cover for a night?

I don't know what type of trailer you have, but my Airstream has a row of rivets running down every stud.

Moved to Tech Issues forum from DIY.

Do the studs use steel-anything in or around them? Larger N52 Neodymium magnets on eBay react to a nail behind sheet wall paneling (the thin stuff).
