I am considering changing jobs ( same field ) and putting myself in the situation where I could travel to a new destination up to every 13 weeks if I wanted to. I could travel to any of the 50 states. So if I decide to do this I will need a new vehicle. My requirements would be: 1.) It would have to be 4 wheel drive. 2.) It would have to be big enough to carry me and 2 to 3 70 to 90lb dogs, I won't have to worry about much of my stuff however. 3.) Pretty reliable and I would like a warranty. Now things I would like would be a navigation system. I know I could get if aftermarket so thats no a priority. I would like to be able to take this vehicle off road but I guess I wouldn't have to. Some vehicles I have thought about are a 2003 or 2004 Jeep grand cherokee, Chevy suburban, tahoe etc, a 2500 sierra, or a used Ford excursion with a diesel. Thanks for your help and I look forward to seeing what you all suggest.
