I've learned over the years that it is way too easy to get distracted and execute one of my own "bonehead" moves. The ramifications of missing a step can cost you money, or worse.
We used MS Excel to create a check list that we both work on together while hitching up. We both verify that each step is complete. It takes all the guess work out of hitching up, and makes us confident that we didn't miss something.
Although the check list is tailored for our personal FW set up, I'd be happy to send you a copy if you'd like to see an example. Just drop me a PM with your email address and I'll send it to you so you can edit it for your rig.
