I'm not Sue, but I had the same questions about the cameras she uses. She actually has details on her website here.
Sue's CamerasWe made the trip this year. Ten weeks of glorious scenery, activities, and animals. It was wonderful. I am still pinching myself to see if I'm dreaming. I can't believe we have been there and back. It was wonderful. And the best part was we met Sue and Steve! Boondocked in their front yard.
We started out with friends in another motorhome. They left for home (medical reasons) when we were in Valdez and we finished our planned trip on our own, including ferry hopping down through the Inside Passage. Loved having friends along, but did fine by ourselves after they left.
