Here is the challenge...bum bum bum

I have an 08 Frontier KC AT SE 4x4. I use it mostly for a daily driving, hauling kayaks, and heading out for hiking and snow shoeing.

Here is my goal. Well I am getting the feeling that I maybe pushing my luck with my truck in stock form. I am looking to have my truck set for mild to moderate off roading but still keep it as much as possible to stock highway mpg of 23. I dont intend on going to no mans land at this point so im think locals that wont require a winch.

So this is what I am thinken is in this order.

Rear diff vent mod
Calmini 2.5 block suspension lift kit
Armoring up with skid plates underneath (undecided on brand)
rocksliders (undecided on the brand) Would like something that looks sexy

Sound like a reasonable approach? At max i currently run into some muddy water that would reach the bottom doors in stock configuration. with Goodyear Wrangler rt/s p265/70r16

In the future getting some mud tires and wheels to be swapped on only when needed.

What u guys think? This is my first truck...im used to modding imports.
