Dang, if that's the shortest you can get now, it makes sense. I used to drive a tri that was only 24'. It was a snubnose IH w/ a 15' dump bed.
I'm with you on not really wanting to be in the dump trucking business. I had a few for 15 yrs, sold all but 1 tandem, and 1 tractor trailer in 2010. With what people will haul for now, I say let them do it.
