Rain and weather is one thing...... what about your $$$ equipment getting stolen? If you're in a development, atleast try and "hide" it under a tarp. I leave my equipment in the back of my dumptruck, with a tarp tied down, then backed up against my garage. They could probably still get mine, but they'd have to work at it, and do it very quietly.
Ever think of getting a van, that you could just park and lock up, also safe fromt he weather conditions.
What type of equipment are you using, wb's? 21"'s?
