How many days for Yosemite, Kings Canyon & Sequoia?

We stayed a few years back at the camp ground in Kings Canyon was not crowded and set in a nice area along the river. Kings canyon and Seqouia are basically co-located, so you can stay in the canyon and day trip to the trees if ya have a towd or small rv to drive. Yosemite is another story as it is larger and requires a bit of movement. If ya cant hike and stuff mainly relegated to the roads and the bottom of the valley. Makes a good motorcycle trip but that is another journey
