I will be flying into DCA (DC National Airport) and need to rent an SUV the weekend of Labor Day. I will be traveling to family in West Virginia and Pennsylvania and will need to have a vehicle with 4x4 due to them living in the mountains off of a very bad rocky, muddy dirt road. I have actually gotten stuck on it in a car before, so that is not an option. I seen on Avis website, they do not mention if it is 4x4 or not for SUV.

Can I be guaranteed a vehicle with 4 wheel drive? I dont care WHAT type of vehicle, but it needs to have 4 wheel drive. I have also not rented with Avis before, I usually do Enterprise, but they cannot guarantee me a 4x4 vehicle. Do they have mileage limits, or limit what state you can go to?
