A response with no dog in this fight. E-One came to Boston in the early 80's to secure a contract. E-One gave BFD a demo rear-mount, assigned to L-17. House was a busy house E-7, E-26 (2 peice with a squrt) and L-17. They ran that rig to death, every deuce in the city, rig did good. At this time every ladder was a TDA most new rigs were Seagaves with bubble tiller enclosure. Good tillermen were a godsend, how do you replace the guy him on his 14 day vacation? I live in Cicero, Illinois, we have a 100' aerial TDA from E-One. Sharp looking rig, we go food shopping on Sunday morning, we run into the rig of of TL-1, T-2 E-3 when the see our house they use the air horn, drives Bear and Austin crazy, especially at 3AM, bad intersection.
