Length of Optimus Prime

[Whisky Tango Foxtrot]

Does anyone know how long the truck that G1 Optimus Prime turns into is (without the trailer)? I'm trying to work out some scale issues.

I can't find the exact dimensions of the truck model, but according to TFWiki, the truck itself is a White Freightliner WFT-8664T cab-over. I only did a cursory Google search, but I hope that'll be a starting point in researching the info you need. Good luck.

I wasn't able to find anything on the Freightliner specifically. I did find this page that gave some dimensions on trucks in general; mostly wrt the trailers, but using the measuring tool in Gimp and a bit of math I was able to work out that the total length is about 7 metres. Since the Ratel IFV is 7.21 metres long and HFTD Breacher is about the same length as THS-02 Convoy (without the trailer) that means that it would make sense to include Breacher in a Legends display.
