>> another has a 550 commercial to pull her big horse van, etc.
Dayum! And I thought I was hot stuff with my F350 DRW! ;-)
She is pulling a six-horse van full of 1500-pound warmbloods over passes through the Blue Ridge, and up and down I-95. She likes to feel she has enough muscle to go up some of those inclines. It’s a seriously impressive rig and we all envy her, but of course the downside is that she can’t really unhitch and drive to the grocery store if necessary, as you can.
