DONT DO IT!!.
I made a reservation weeks ago and go into a Budget location in Austin tx to find they have no trucks available. The customer service guy said that our reservation doesn't reserve the truck just the price. So, we had to go all around Austin and surrounding areas to find a truck available. We finally found something but had to drive 20 minutes to get it. You know who ended up helping us... UHAUL! Don't waste your time because reservations dont reserve anything!
