bought the 09 crew cab sport with the big boy in it, in august. That thing is a boat towing freak
the tow mode is great, drops you down to 5th max instead of 5 + overdrive, engine breaks when you are slowing, feels like it adjust you shift points as well (but i might be talking out of my butt on that one), and it turns off MDS (multi displacement system - shuts down cylinders based on driving conditions automatically)
You can absolutely feel the V.V.T (Variable Valve Timing) work its magic while towing. I think this is my favorite feature of the HEMI. Towing a 4000# is a complete breeze. Not a whole lot of up and down shifting on the HWY.
ESP and trailer sway control makes towing stupid easy. You can barley feel the boat. I'm gonna be real honest here. The hardest part about towing in that thing is going the speed limit, and remembering you have a big A$$ boat dragging behind you. caught myself cruising 80 a couple of times on long trips. The new rear suspension feels like a car, no bouncy BS.
I wish i didn't sound like a commercial, i wasn't set out to buy a dodge or a dodge this big. But it after I went to all the comps. and looked at them pound for pound, $ for $, this was the best decision i could have made. Easily the best truck i'll probably ever own.
GET the rear cam. ROCKS!!! i can literally back into the trailer and match the hitch exactly on the first try, every time, WITHOUT a spotter or ever getting out of the truck. Probably reduced the wife's hook up time by 5 minutes! and my stress level to zero.
And it doesn't hurt that i got the lifetime warranty. that was the deal maker for me. But i'm pretty sure its only for '09s
i'll post some pics hooked up and show you what the a$$ drag looks like.
