nothing too complicated..ARB commercial bar, snorkel, brown davis underbody all the way through, recovery points, 2" OME lift and Micky T's all around. Inside an ICOM, set up DVD players for the kids and use a HEMA and a security system (ive had cars stolen before).
no problem with sourcing any of it or reliability, tows a camper trailer well, heaps of room, economical, drives well, done lots of sand and a few more difficult medium rated tracks without issue. Its been a great tourer but I don't think the D40 would ever be a serious off roader.
