Jayco used ST screws with drill point tips. I've found them through the chassis of our Ford E450. Once IN, they break off at any attempt to back OUT. They must have spun them in with an air tool going about a million RPM. I'd drill and tap as noted above. Make a stop for the drill bit that allows it to just get through the chassis rail material.
