I’m looking at a 2020 very low mileage service truck. 33k gvw, 14’ box,etc. problem is that it has the paccar px-7 (Cummins 6.7) set at 300 hp with an Allison 2500 transmission. All the trucks I’ve had in my career of this size had the px-9 with an Allison 3000. My concern is that once I load it up to roughly 30k it will be a major turd and if I crank up the hp it will overwork the transmission. Any thoughts or experience or advice?
