New to the tacomaworld in more ways than one

About a month ago I bought a used 2015 Tacoma. I've done a few simple mods but am wanting to get a lift so I can run 33" tall tires with as minimal rubbing/trimming as possible. As the title forshawdows, this is my first Tacoma and even first 4X4 truck so I'm new to the off-roading world. I noticed the other day when I parked next to a same year Tacoma with the same size tires (265/75r16) and a spacer leveling kit, I seemed to be sitting at the same ride height if not a little higher. However nothing on my truck stands out that isn't stock, such as a spacer.
1: Is anything already done to my truck as to why I'm sitting just as high as one with a spacer and more aggressive tires(or am I crazy)
2: What is the best lift options for me to run 33" as stated. (Money is not necessarily an option as I'm not going to sacrifice quality to look cool, just might have to wait longer to save)

 

Looks like you have bilstein 5100's. They are an adjustable shock and that is why you sit higher.

Here is a YouTube video explaining the function and adjustment:
