You misunderstand. My 30 is plenty long enough. I already own this trailer, but if/when I upgrade, it will be no longer but most likely quite a bit heavier. I will NOT go back to BP. Been there done that for many years, and the handling difference is remarkable, so BP is not an option I will consider.
Also if we do upgrade the trailer, in the 30ft class, I do NOT want weight to have to be a consideration. Besides if I wanted another gas truck, I would never have started this thread. It was more tongue in cheek, the comments on the stroked 350's. I looked but wasn't serious.
I am seeing the '06 GM's in the 75K range for mileage, so I would expect another 200K before anything serious to come up.
