Pre-trip inspection on class 8, thump each tire, turn on all lights and signals, check air hoses, glad hands and brake chambers, make sure the landing gear is fully retracted, king pin jaws locked? I check the duals on my '57 when I take it out, and the lights. Someday I might wire the back-up lights, they are integral to the taillights but I didn't run enough conductors to heat them up.
