Good day to you all. I'm based in the UK and am on my 3rd RX, first was RX400h, then the RX450h and from this Feb the RX450h Luxury 2013 version, which I must say is my best yet. However, I have recently purchased a caravan (Trailer?) for touring. I have done two trips so far BT I have various concerns and maybe I could get some comments. Whilst the car will tow 2 tons and my trailer is 1.5 tons, there is no problem there. However, the tow ball downward weight limit is 80Kg (176lbs) and this is quite hard to achieve without putting weight behind the axle of the trailer to counterbalance the nose weight. Does anyone have experience of towing the Bailey Unicorn Valencia 2011 with an RX450h? Also, I inflate my tyres to 33 psi, is this correct? The other question I have, is it better to tow using the sport mode that increases torque but does it stiffen the suspension? I would really appreciate any advice or suggestions. Thanks
