Ron -
Too funny ... and true.
I am the same way with most things. Thought-out to the umpteenth degree and then precisely executed.
If it turns out that I need the booster with my short 1575 & extended cab truck then I'll probably mount a water-proof box somewhere under the TT, but as far as powering it I'll probably stick to the roach, er alligator clips on the terminals as I have nice & quick access to my battery at all times (no crazy sliding tray setup on my '14 Lance TT). Since the booster is only needed while towing I don't want even the slightest parasitic draw from it while it is "sleeping" while camping as we are dry campers 98% of the time.
