There isn’t a hill I’ve been on that I would be afraid to descend pulling a 16000 lb rv with the 7.3 gasser. Low gear and 6000 rpm is a lot of engine braking.
You are a brave lad !!! Can't argue the fact of what a 7.3 gasser will ,or will not do , but I towed a fairly heavy fifth wheel many years with a 7.3 Powerstroke , no EB . Had a few white knuckle experiences coming of some of the hills in Utah, Idaho ,and Montana . Yes learned pretty quickly on how to come down some of those long grades . One example is the one coming from Ennis,MT to Virginia City , MT. It has the runaway ramp if needed .
The ability to rev to 6000 rpm; work against a closed throttle plate; and the torque multiplication of the 4.615:1 low gear ratio all work together to give the Godzilla a massive advantage over a 7.3 diesel when it comes to holding a trailer back on a long steep grade.
