Toyota Kluger?

Is it the new Kluger or the older model ?? Friend of ours have the older model/shape. They have 3 kids,15,13, and 8 and tow a trailer with a heap of gear and have no problems. They have taken it to Stockton (without trailer) but dont take it any where off road bar simple bush tracks which you could drive a commodore or falcon down. The new Kluger has heaps more power 200kw the old one I think is around the 130 mark. The only issue they have with theirs is the bum gets a bit saggy when they are fully loaded but as far as been capable no worries. I dont see you having any issues what so ever except maybe the rear end dropping down a bit but if you find this then Im sure a pair of air shocks or some thing of the like will solve the issue. Best thing is to load it up camper and all full tank of fuel and see how it sits, if hanging down too much them I would do as I have said above (air shocks or the like). Regards steve M
