Three axle rigid - does dropping rear tyres help cornering?

Tailschwing:
The wagon we were in at the time the guy said that was a Daf Euro 6 with a droppable box I think - I do remember him saying it had rear steering. One I was in today was a Renault.

Yeah, it wasn’t fun driving it down sidestreets in the city centre having only driven one a few times - tight enough in an 18t!

Depends which city centre & which streets
