DC is a great place to explore. But it is darned hot in the summer. We spent 5 days and really didn't cover all there is to see at the National Mall and the Smithsonian Air and Space Annex. We stayed at Cherry Hill in Md which seems to be far and away the most popular CG. They have a bus which takes you directly to the train station and that runs you right down to the Mall. You do not want to drive in DC.
The greatest altitudes I suspect you might run into are probably in West Virginia if you go that way. Just tall hills actually and nothing compared to the west.
I agree with what they said. We used the same campground and it was HOT!! We did a week in DC at Cherry Hill. It was a lot nicer than I expected for being so close to DC.
As for elevation - I really don't recall anything being too bad headed out that way, but after a few trips out west, everything else is just a hill. Although I have an F-350 with the diesel and haven't seen the transmission temperature move more than a few degrees. I expect that if you stay on the Interstates, you'll be fine. Those were designed for reasonable grades, no worse than you'd see going to Nashville.
We were there for July 4th and sat next to the Washington Monument to watch the fireworks on the mall. Awesome times! Lots to do, with all the monuments, Smithsonian, etc.
Don't forget about the National Zoo.
