well had my first tow with the Galaxy last weekend and I am well impressed no lack of power and returned 28mpg much better than the old Pathfinders 17 !!! Gonna go for 18" wheels when current tyres are shot but not sure about lowering as the caravan sits nice and level as it is now. Just checked the plate on my van and its weight is 1723kg according to parkers the Gal is 1724kg so thats a 100% ratio but towed as steady as a rock , Max tow weight for the Galaxy is 2000kg so i'm well within that.
