Hi Eric...
Here's my two cents.
At work, we have to drill holes in frames all the time to install
hitches. We use a regular floor jack that has a weird plate that
cradles the drill and we use it to press it upwards into the truck.
works awesome. good luck

The U-Haul trailer rental shop nearby has a tool made just for that job.
IIRC it was like an inverted drill press with a long lever.
