I've had several loads that I was called on because I had 24', and the 22'er ahead of me wasn't enough. I think it matters who you run for (how important it is to them that you are loaded) and what kind of freight they haul. If you run for an unspecialized company where you're just a number, they tend to rarely take things into consideration such as the extra 2', liftgate, or the fact that you can haul some semi freight. So, IMO, every little bit that helps put freight on my truck, I'm all for it... as long as the benefit outweighs the cost.
