New owner 2016 2500HD WT

[Charlie2500HD2016]

I have a few questions from you the more experienced ones.

To level the front end you go under the truck door and tighten the bolt on the uplifting key? Is there two? What size socket?

In the engine compartment on the front right there looks like a battery space. Can you install another battery there? Where to run the wires?

Everyone speaks of 18 and 20 inch tire upgrades. What is the largest tire in the 17?

Where to get a key Fob?

Thanks

Congrats on the new truck. There is a spot for a 2nd battery but you will need a wiring kit. Key fobs can be ordered online, but must be programmed at the dealer.
