Hate to be a pedant, but no Dickens books are over 1000 pages in standard modern printing. My Everyman edition of Our Mutual Friend (which is typical) is 822 pages. So, you don't have quite so much to read as you thought.I'm currently reading Our Mutual Friend.
The pace is quite plodding to start with, however I am enjoying it without overdoing the reading. I read a couple of chapters then do or read something else. At over a 1000 pages you've got to take it easy.
