Finding Studs Behind Exterior Aluminum Siding

The framing in this trailer is wood constructions with aluminum siding. I tried the infrared temperature gun suggestion thinking there might be temperature variation between stud and insulation between studs. If there was it was not enough for me to have confidence on stud location. Tried the knock test. We will be going camping in a week maybe I will be able to see with the dew method...

I was thinking of using the smallest drill bit possible and find the stud on the inside and drill all the way through to the outside.

I was thinking fiberglass sided. If wood studs, that *should* be super easy. The luan paneling should be stapled to the studs and vertical rows of tiny staples should be visible if you look close up. Look for the tape they use over adjoining seams in the sheets of luan and then look for studs like around 12-16"+ away. Studs won't necessarily be even spaced. I tried a stud finder once and didn't work well. Pushing on the luan to see where it does and doesn't flex can be a clue. Carefully tapping lightly with a hammer can also work. IR gun won't work as well on wood studs but would want to try in early morning with interior warm.
