3. Always always always do my own routine when prepping for launch. Even when I have help available.
5. It's always best to be patient. After all I could've been stuck working.
#3 just trips me out. I truly feel your pain. Takes me two minutes to do my routine alone and 10 minutes when someone helps because I either have to redo or adjust something.
On top of that my SO at least pulls the boat out of the water. After I back and set the trailer in the water I roll all windows down including the back one (Tundra, full roll down back window). I'll pull the boat on, strap, trim up and the wife pulls us up so we're out of the way of the ramp. We rig the boat for travel, I hop in the truck and all the mirrors have been adjusted for the wife. For a 50 to 100 yard straight drive...
#5, definitely an acquired skill.
