I had a D5 XC70 2012MY and towed a 1800kgs caravan with it. I always used D unless I wanted a bit more squirt on the hills. It is unlikley to bother the gearbox whichever you use and maybe not much difference in consumption either. I would just use whichever feels comfortable for the car. I found the best speed to tow at was around 57mph as it was in 6th gear and just under 2000 revs. At that speed on motorways /A road and dual carriageways it was happy to stay in 6th unless a steeper hill came along and then it would change down a couple of cogs if the hill was quite steep.
