It will get easier w/time. I've been hauling for years, but I never forget that my babies are back there. I was nervous though when I moved them from CA to AZ-that was a long drive & I was glad that hubs, BIL & FIL were also pulling trailers so I wasn't alone. I did have our 2 shepherds in the cab w/me, also. Hubby had the crated cats w/him.
