No room for a TOAD if you are staying at Crane Flat. It is barely possible to manuver the RV around without a towed vehicle, that goes for anywhere in the park. And, if you are staying in the valley, you dont really need a TOAD, because the shuttles come to your campground.
We were having lunch in the RV in visitor parking. This family pulled in, they were driving a dodge 3/4 ton crew cab, towing a 25ish foot Sandstorm toy hauler. They pulled in and got stuck. Not stuck in the mud, but they couldnt back up, couldnt go forward. They clogged the parking area. A tow truck came in and dragged it around to open up the exit. We later saw the dodge being towed out of the park, followed by his trailer behind another tow truck. What a disaster. And there is no way to know. You follow the signs that say visitor parking, so you go. You dont know that once you enter, you are never getting out. So, bring a TOAD only if you have a site in the valley, and you dont want to ride the shuttles.
