I've been driving an EB as a daily driver for over 25 years (drove my '73 today) in every configuration you can image (6" lift with 40 ground hawgs, stock, 3.5" lift with 33s, etc.) and have put up with a lot of noise, heat and thin wallet syndrome, BUT, it has always been fun for me. NEVER GOT 20mpg in any of them, but got close in my '71 with the 6 cyl, but not 20mpg.
As I near the big 50 in the next few years, however, I have contemplated getting a beater gas saver and only driving the Broncos on the weekends..... hard to make the switch at this point though as my kids love being taken to school in a Bronco. It it is a life style choice I guess (gee, never thought I would say that)!
