Congrats!
When I went down the same path as you, I found that there isn’t any info.
Had to use a stud finder, and then slowly use the hole saw to get through the wall paper/luan to make there was no stud. Once it was clear, drill away.
I hit the right spot the first time, so it went beautifully. Have cut dryer holes in 3 RVs now, still a very nerve wreaking experience
