I'm in NE Ohio three miles off of the turnpike between Cleveland and Youngstown. You and your pup are welcome to stay in our old camper, (electric but no water), or you can stay in our spare room as long as you can tolerate cats and cigarette smoke. The dog, though, would have to sleep in the camper or garage, because our cats would probably kill and eat him, LOL!!!
We're not fancy, but we have a clean, comfortable home, and I'm a decent cook. My husband does prtty well on the grill too.
My brother lives in NW Maryland and loves to ride his motorcycle. He may want to accompany you for part of your trip if you're in that area.
