But I believe with the 2011 GM models, they'll be adding an exhaust brake as an option.
You won't be disappointed with the Banksbrake. It's night and day over towing without it. We are beginning fulltime in Feb 2011. See you out there somewhere.Looking forward to towing with it and seeing the difference. We tend to spend a lot of time in the Rockies in the summer and I've had enough white nuckles coming down some declines and using up the truck brakes. I see you have ordered an 2011 BH 3670. We ordered ours in March and have been full timing in it since May and are very pleased. It had a few bugs to be worked out but that's the norm with any RV; I don't think you'll be disappointed.
Be very careful of ANY exhaust brakes UNLESS factory. They will absolutely blow out your truck if not installed exactly right. After all the problems the aftermarket brakes have had and the problems they have created it is amazing to me that people still buy them!
And depending on the age of your truck, it will void your warranty if they can prove the add-on is the cause. Doesn't matter who's name is on it, Banks or Joe-Don-Looney, you're screwed.
