I purchased the $19 special rechargeable 3/8" drill at Harbor Freight. It works fine on the screw jacks for the stabilizer feet and will take the slack out of the Hensley adjusters. Then I tired to drill a small hole.
The chuck sounded like broken glass when turning it to tighten on the drill bit. I could not tighten the chuck enough to back out the bit. I went to the hardware store and acquired and installed a Jacob chuck that cost more than the entire drill with battery. Now it works just fine for both jobs.
I also purchased a 3/8" speed wrench at Harbor Freight and found a 3/4" swivel socket for a 3/8" drive. I now have a speed wrench that is about 10" shorter than the one that came with the Airstream. That is important where we store the trailer as sometimes there is barely 20" between units.
