As far as rear axles go, you can get away with much less than a 4.10 rear and pull a ski boat. Obviously, a 3.73 or so is preferable though.

Edit: Sorry, I'm reading backwards on this thread. What does Chevy offer? A 3.55 or comparable?

I found out (a little late) that my expedition has a 3.33:1 ratio. Didn't even think to look into that when I was shopping for it and might have kept looking had I known. I added a tranny cooler and it tows the boat quite happily with no ill effects and no struggling. It's rated at 6,500 lbs with that rear axle ratio. I think the 3.73 gets it to 7,800 or 8,000 but I'm struggling to remember what I've read at this point.
