This van passed me earlier today on Hwy 75 between McKinney and Sherman.

I give up, what is a Tech Van?

I’m guessing there is a Sig armorer in there.

I am not sure what the tech van is. I saw it approaching in my rear view mirror and it blew on past me.

It is something that is relatively new By Sig. These trucks are sent out to their dealer shows and SIG events for marketing purposes. They aren’t really “tech support” for firearm repairs. More akin to dealer & sales support
