It has the 3 leaf spring pack. One short one on the bottom, and one clamped front and rear to the top spring mounted to the frame. There is no auxiliary. I'm guessing the the 10,000# rating means one or more of those springs are heavier than they would have been. Not sure if the lighter config would have come with just 2 leafs.
So, I've had a lot of experience with trucks from 1/2 ton to 1 ton. Short bed to 8', and extra leafs and air bags, so am mostly looking to see how closely someone might have come to my truck configurations.
The camper will be off the truck more than it's on.... for now. Down the road, that may change.
I'm fairly certain that the stock setup will handle the 7' camper we plan to order, and I'm fairly confident that if we put an 8' on temporarily, it will be "OK".
I'm guessing the air bags aren't essential, but I've had great luck with other rigs where having that extra support has really helped level it out if/when needed and has seemed to help the ride/handling.
I'm concerned that having an 8' camper on a 6.75' bed will put enough weight further back of the axle, that it will affect both ride and handling. Was hoping maybe someone had tried that configuration. That's something I've never had experience with.
Thanks for the welcome and all the feedback so far.
