Kudos to GS for bringing in the tag axle. I wonder why they didn't up the engine to the 450 Cummins, or 500.
By the way, those of us with the 400 can have Cummins reprogram the engine to 450hp. I had mine "campaigned" by Cummins due to the faulty wrist pin letter.
The shop manager told me the HP increase is a electronic module programing issue, and they just happen to have the electronic equipment. Cost was $2000, so I passed.
But, if I was pushing a larger coach, with more GVW, the increase might be nice.
I also will not be upsizing. This 42 footer is treating me well.
