Glad to hear you enjoyed your first trip. It will get quicker setting up as you get into a routine. Don't worry about the speed of 50MPH, there is no rush to get there and the important thing about towing is not only pulling the van but being able to stop safely as well.
Keep on enjoying it, - home is where you park it! 2011 XS SD4, Indus Silver (Getting to love it more and more)
