I love Ardnamurchan. We've visited it in the last few years both staying in a cottage and cycle touring, but not by campervan... yet!
Good to see another Jerba owner on the forum - we've had our Sanna for just over a year now and think its brilliant. There's inevitably a leaning towards the Cali on here (so the odd thread such as "Inferiority of Conversions" can raise the hackles a little

), but regardless of that it's a great place for all sorts of useful information and tips.
On bike racks we didn't bother with the VW one but simply fitted our existing Thule Raceway to the tailgate (with the upgraded tailgate struts). Only 2 bikes for us (there is a 3-bike model) but it's neat, compact, stays clear of the reversing camera, and doesn't obstruct the rear view very much at all.
