Couldn't find a place to put this question! Hoping to take a 400 mi round trip around a week from now, if I can get the wrinkles out of my plans and my Ex! Need to get a jack, jack stands, a tire inflator, maybe an extra battery for camping/possible jump start, later a trickle charger and small cooler. What do you like for jacks for instance? Walmart, Harbor Freight, somewhere else? Low budget but don't want something that breaks/is hazardous.
