Use the icon that looks like a tape measure to get any measurement.

For changing views and just exploring the trailer use the icon that has a red and green arrow going around a vertical rod, then move your mouse around and you can rotate it in 3D.

Hope this helps and my apologies for not getting this posted sooner.

Hello Bill,

would you please remember what was the thickness of the material used? I am asked to build a trailer like this.

Thank you in advanced.

Greetings Pavel, I will go and measure tomorrow and let you know.
