Seeking V2 dimensions

Hi, can V2 people confirm a few things?

exact exterior width from extrusion to extrusion (not including the original mounting brackets)

what are the T slot dimensions of the lower extrusion?

Fabricating my own mounting interface (non supported vehicle) so I’m hoping to fab gutter mounts that bolt straight to the sides of the t-slots.

also, is the tent portion of a V2 Platform camper the same dimensions as a V2 RTT?

thanks y’all
