Questions about moonroof, and SR5 vs TRD price difference

Two questions, spent all day hitting the four dealers in my area.
1. Does anyone know if a moonroof is a factory or dealer install.
One dealer said he can put one in inhouse?

2. I like the SR5, has what I need and is simple enough. Wife likes the a TRD PRO.
Looking for opinions SR5 vs TRD. Is the $10,000 difference worth it.
I will not go off roading, just need winter snow traction.

I know it's up to me but I would like some opinions.

Thanks for any help.

 

Moonroof is a factory install.

 

Just a word of warning the moonroof eats an inch or so of headroom, if you're tall or have a longer torso make sure you sit in one of each it could be a deal breaker for you. I have a trail premium that is now called the TRD Off Road, I like the options, they just make it a little more comfortable, I also have the KDSS, ads a bit to he price but the handling on road is worth it to me. I did not want the Pro.

 

Pulled the trigger today. No moon roof. I'll live with it.
