Good choice. A piece of advice that I would give you is to replace the four 'webbing' guy straps that are are supplied to to pin down the side with the main entrance and, assuming you use an awning rail and 'figure of 8', the side that fixes to the van until you drive away (and the tunnel is stowed). They are a pain in the 4rse to get to the right tension so I bought 4 new straps with cam buckles which are a hundred times better. Hope that makes sense!
PS. Also, get yourself a couple of cheap awning poles and extra guy lines to hold the main door up. Good luck with driving away and parking back in the right spot again - it takes a little practise but my tip is to use two tent pegs and a length of fluorescent guy line - the pegs are to mark the centre points of the tyres when you reverse using the guy line as a guide.
