Everyone on this site has been super helpful and I hope you can help me out again.
I'm booking my rental car for my family's week long trip to Yellowstone and Grand Teton. There are 4 of us -- 2 adults and 2 teen boys. My oldest is 6 feet tall now and, given the rate he is growing, is likely to be a few inches taller for our August trip. Therefore, leg room in the backseat is a big consideration. If I rent a large SUV, like a Tahoe, will I have problems parking the parks? We own a full size crew cab pickup so we are used to driving large trucks but I'm not sure how spacious parking is at various pull offs in the parks?
