Forkliftaction.com's Industry Forums are not only a great place to swap ideas, ask questions or comment on recent developments, they are a great source of story leads for the editorial team here. Last week, we picked up on some heated debate about trainer liability. This week, US correspondent Roger Renstrom delves into the forum chat about the trade-off between performance and emissions controls - and with some expert input, deduces that you can be lean, mean and clean - all at the same time. So if there's something you'd like us to pick up on, post it in the Forum.
