Turns out, all I had to do was lower the tail gate...and get the hand truck under the back to ease it back far enough so the end of the box was on the ground. The Connie drove the car and trailer out while I hung on to the crate which slid easily down the tail gate. Oh...we stopped at a nursery while we were in Arlington for some green things. (Note to prospective builders: keeping your wife happy through this long process is a constant challenge...these things help.)
