2016 Rear axle outside hub face measurment help

1. Hello All I am reposting this here under the advisement of another member because they don't believe where I posted it originally will give me an answer
   
   I would like some help,
   
   A brief background - I was the proud owner of a 2016 TRD SPORT DC 4X4 until an uninsured motorist hit me head on at 35 MPH "because she was very busy texting and driving" and totaled my truck. Fast forward to tow months down the road and while my uninsured motorist has kicked in I am still without a truck but one is finally one the way.
   
   While I am waiting - I want to make a enclosed weather tight trailer to pull behind it to have when my son and I go camping up in Colorado to keep all of the rest of our gear and supplies in it, as I found out the bed alone does no quite hold 14 days worth of gear for the environment we are in and have to be prepared for.
   
   What I need to get the rear HUB FACE measurement so I can make the trailer track the same as the truck. The next time any of you folks have your rear tires off would someone be willing to measure the hub outer face to hub outer face face and provide it to me. I have called Toyota and even asked my local dealerships and offered to pay for time to pull one of there new trucks in and measure but they all have said nope. So sorry to bother you all, I realize you all probably have much bigger fish to fry, I just can seem to find it anywhere and trust you folks over the varying answers I'm seeing online.
   
   Thank you in advance
