I'm told my '15 will be built on 16 October. Coming from a G56 manual shift I've been wondering about the Tow Haul mode. I assume hauling no more than 5000 lbs I'll always have it engaged. What exactly does it do, lock out higher gears or raise RPMs? Just wondering, thanks.

If you're towing a heavy load and NOT in tow mode, you may find your transmission hunting up and down trying to stay in a high gear. This is hard on an automatic transmission. When you hit the tow mode button, it stops the transmission from shifting into the highest gear. When you're on rolling hills or a steady incline this is much easier on the entire drive train. When you coasting along on a flat road, and the transmission is fine in high gear, then you don't need to be in tow mode.

I tend to leave it off until the truck tells me it needs it.

I honestly just turn it on and forget it when im towing. Iv noticed the ride was just smoother towing my boat. (4000Lbs fully loaded)

Be careful...

Just incase you're unfamiliar, I would hate to see something go wrong with your new. I would recommend a good break-in period before trying to move that kind of load. Also, make sure that's on a trailer and not in the box. Not sure what your moving but our trucks unfortunately have a low payload. Oh the trade-offs...:(

Congrats on the purchase though!

DC if you're talking to me I didn't think 4800 lbs was that heavy of a trailer for this truck? So these truckss should be broken in? I thought pulling a load helped to seat the rings and assisted in the break in. I have called the dealer and told them to include the air bag suspension to keep truck level.
