I find myself wearing the same comfy casual dresses over and over. Easy to layer, no binding while on the road. A simple shrug and chunky necklace can dress it up for times you might want to feel more 'presentable.' You might also check into clothes designed for travel - often lightweight knits. Tencel is another forgiving fabric. Look for things that will take little storage space and stay relatively wrinkle free (or totally wrinkled, like gauze). You can either attempt to coordinate everything, or just go with gaudy! Undies that dry quickly so you can do hand washing if need be. A good hat you will actually wear - I find ones with front bills rather than all around brims work best for me, so I can lean back in the truck or camp chair. For feet I pack flip flops, flats, hikers, and outdoor slippers.
Yes to the walking sticks, I have one my son made from a twisty branch, and my husband uses an old ski pole. Great for balance, I just can't jump over those logs quite as nimbly anymore! Our camper has a long side slot for fishing poles and such and that's where we keep the walking sticks. As you get used to your rig, you will quickly establish 'spots' for different things.
Invest in a couple good comfy (for you) camp chairs. You will spend a lot of time in them.
I would love to travel to the east coast at some point, but for the time being we are hanging on the west side. I agree with Rosie on the SW desert, too hot and dry for my taste. But beautiful. My aunt winters in Arizona and keeps telling me the 'dry heat' is different and I will love it. Hmmm. Nope. I'd rather have humid heat and soft elbows than that lung-searing heat that cracks your lips and feet. But, everyone is different.
