Hi 973, My cousin and her partner have a 4wd Hilux it has a trayon camper on the back and they tow a heavy duty boat trailer with a 4,2m tinny on it, to me its one of the best set ups I have seen for two people traveling around aus or anywhere, They unhook the trailer back the 4wd in to there camp spot wind down the legs on the trayon camper then they have a empty 4wd to tow the boat around, They stay at Pennefarther for up to 3 months, They have done the lap with it a couple of times and had other things but this to them is the best set for them as they love fishing not sitting and drinking, Pity they are so dear or I would look at one when the time comes to head of with the wife, I think they weigh between 370 to 440kg so if you have Ally track back 4wd should have heaps of lee way on weight evan towing a good size 4,5 to 5m boat and trailer, as you can always put some gear in the boat, Craig
