The day a bag of powdered tile mud split open in my trunk was a day that truly sucked and put me on the path to truck ownership.If you're not quite ready for a truck's gas sucking issues, try a foldable trailer like this:Foldable TrailerTakes up very minimal space in your garage and when unfolded and a sturdy piece of thick plywood as the base, works really well for hauling around stuff.

Simon L'Grie is my hero.EACH month I've been issuing a notice...from them trying to hide a cat ( liter box under a pile of dirty clothes, ( 12 foot by 12 foot two feet thick/deep, all in front of a $2K washer dryer...yuk....to the boyfriend trying to kill my HVAC by setting it at 62 degrees during 105 degree weather..he works nights and likes to sleep under blankets...all summer long...with free cooling.

I suggest you get some fire in the belly and the eye of the tiger, you also need thick skin in RE.
