20 4WD’s OK on a wet bitumen road isn’t it?
Depending on what type of 4WD you own will determine whether it can run on the blacktop in 4WD or not. A constant or full-time 4WD has an on-road mode that works on bitumen without transmission damage courtesy of an unlocked centre-differential. Plenty of high-riding wagons use this system because back in Japan, Europe and the USA they have ice as part of their environment risk and a full-time system can cope on the blacktop, wet or dry. With the ability to vary drive front to rear, they avoid the wind-up seen on part-time 4WDs that loads so much tension on bitumen roads, that it can smash transmissions leaving a serious repair bill in its wake. There are precious few dual-cab utes that are full-time 4WDs, so you want to be really, really sure you know what your machine can do before you pull the transfer lever or push that button. Ouch!
