There's a LOT of stuff to remember; and sometimes a specific sequence of events. It might be a good idea to create a list, in sequence, modify it as you learn, and use it until it is internalized. e.g. First two things once you are in place, 1) leveling blocks 2) chocks, etc. The same with pulling out. Reverse the list. And walk that trailer a second time after you think you are ready to pull out. That has saved me more than once. e.g. Once I forgot to raise one of the stabilizer arms for what ever reason; got distracted I guess. If I had pulled out, it would have bent and ruined that stabilizer. Just take your time, think it through, and double check. It saves accidents, damage, injury, etc. Best of luck and have fun.
