Since the roof hasn't needed any protection visiting 40+ countries, why now? Don't forget that one has to get up on the cabin roof by stepping up first onto the cab roof and then crawling onto the cabin roof. There is no rear ladder. Any raised obstruction on the front of the cabin roof will hinder getting on top.
Getting to the top is already there, you just don't see it...
Access is over the driver door...
From there getting over the shield will be simple, even from someone as old as Ken...
