Don't forget the protective pads and dollies when renting a moving truck. The dollies are necessary for moving the big items, unless you want to risk a hernia, and the pads are ideal for protecting furniture. Both are relatively inexpensive additions.
When you're purchasing extra insurance for your rental truck, be sure to get everything in writing, and make certain of the basics. At the very least, be sure you understand what's covered, the size of the deductible, and whether the coverage extends to other states.
