Taaadaaa! Took the plunge. Airbags on the Class A

Thanks I can try that, I was thinking of pilot holes, just wasn't sure my RYOBI drill has enough ummph for the job ahead of me, only got one battery, a replacement with little use, I better put it on the charger for a top OFF, RYOBI 18V ONE+/one plus battery (3000 MaHr18v , 54 watt HR) with pilots I do drill each hole twice, but less work per drill cycle, your right enlarging is easier than drilling straight thru with the larger bit
Thanks for the reminder
