Not that I'm picky Brett ( and others ).
I am not too sure ( Kev ) about putting extra air in the tyres to compensate for towing, after all, you only should have a max of 200lb ( or equivalent in kg's ) on the tow ball anyway. That extra weight doesn't mean much in a 4 x 4 that has a 1 tonne payload capacity. Further, upon travelling, the tyres built up heat which in turn raises the tyre presure, anyway.
Brett, you know that someone you know has always got a Nissan, for sale.............. should you ever consider, moving UP in the world !
