To rfhago s point, a mild dual disk Southbend like a DD3250 is smoother engagement and less pedal pressure than a stout single disk like an OFE, in my experince.
Not necessary to go with a DD clutch for the application we are talking about, but now that I'm on my second single disk SB clutch and having driven a few DD SB clutch trucks, I'd go DD from the get go.
Of course my single now rattles more than any DD clutch. Southbend did me a solid when I wore out the OFE and made me a one off full ceramic (buttons) single with a 3600lb pressure plate in an old school 3 finger design with roller tips.
Takes a lot of leg to disengage it, but it holds like no other single I've seen and rattles so loud with the rollers that my CR sounds like a 24V idling with the clutch engaged!
And the price was right. $500 + shipped to AK because the Rep at SB thought my clutch didn't last as long as it should have. Got 85kmi out of it only.
Lifetime SB customer here after service like that!
