I ran a 2400 in the yeti and loved it. But keep in mind, you gear ratio changes that stall. The stall of a 2400 will only be 2400 when yer in 1:1. If you go 2:1, yer stall goes to 1200 rpm... that makes sense right? Well, when i was in 5:1 of my stak, it wanted to drive thru the brakes like crazy, but if i'm stopped, i just throw it in neutral or park. I could hold the brakes and keep it from moving, but you could tell it wanted to go. It was great when i wanted to creep up a rocky trail or ledge, it would just idle right up.
I will go with a 2400 in the new rig as well, cuz i got used to it and like it. I would recommend an 1800 for you Rob. But if you hate it, don't blame me, it's a huge issue of personal preference. It's not that hard to swap out of you hate it tho really.
I ran a nice derale cooler with built in fans, let me find a pic of the model i had. I ran a trans temp gauge and it never got high, even with the flogging it endured...
