Gosh, I’ve drilled lots of holes in my RVs! Sometimes even cut larger openings for things I want to add. I have even drilled holes in the top of my dashboard to hold my GPS more securely than just a sticky pad could. I just try to do it neatly and carefully. The first cut is the hardest! I found a paper towel holder at Menards that has a light ratchet mechanism so that it can’t unroll itself while driving. I mounted it with screws to the bottom of the upper cabinet and DW likes it a lot.
