My bad, made some assumptions. Usually when someone gets fairly defensive over criticism it is related to a desire to be affirmed/right/those kinds of things.
You did ask some very basic/pointed questions at the beginning (a few that could be answered with some thread digging) but I can answer a few of them with opinion/assumption/fact jumbled together lol:
1. why does he have dual shocks? So it looks more fancy.
You want to dampen movement, not cause it to cease altogether.
2. how is the rear frame metal? or is that paint.
paint over metal. unless you mean the bed cage thing, that is plastic
3. the wheel hex nuts are they wheel spacers to widen the stance? I was wondering when I saw them for sale also then I seen them on this guys build
yes those are wider wheel hexes. I run them on both of my rigs. Downside is they come loose a lot and I've bent the pins several times on the 3s rig. Upside is stance is cool.
Here they are for sale

4. skidplate looks aftermarket
it is
Now the cpl question I have left are
RC4wd mudslingers VS SS boggers
Boggers if you are into scale, the mudslingers are not as scale. Personally I'd skip both and go with 1.9 Interco TSLs
I will be mostly rocks and streams not as much mud but will see some . generally ill be doing everything with it but again im set on the look.
They actually suck in mud even though they are sold as a mud tire, unless you cut some of the lugs out. They get packed and turn into glorified drag slicks. But they do shine on rocks with the right foam.
