Seen this twice on the motorways now, came past the other day so grabbed a couple of pics to try and figure out what it was when I got home. Is clearly clad in coverings to disguise it as all new models are when being tested. Looked like a Volvo at the time due to adblue/exhaust arrangement and the reg confirms it’s an FH on a vehicle check website so presumably it’s the new one.
Anyway, thought some truck nerds may find it interesting.
