I have actually been entertaining the thought of a Motorhome recently.
I really am getting old ! 
Well, err, I was toying with hiring one next year and doing a 2 week tour around the top of Scotland.
I'm pretty certain camper vans ain't for me, so I suppose if I tried one for a holiday I'd know either way.
Let's guess, going to do the fabled "500" with all the other wannabe Rob Roys, and try a bit of Haggis and have a wee dram..
It isn't for you TB, trust me, all the tinkers bumbling along at 50mph, stopping without indication, O and you wait till they see anything bigger than a fly coming towards them.
I purposely wanted to avoid the 500, though any route covering that area is obviously going to follow bits of it.
Ironically, when I was up in the highlands last month, getting about was easy and fairly quick, despite a lack of roads. Everyone drove at the speed limit, or pulled over after a mile or 2, bar the odd camper van. That ease of getting about, added to the fact the scenery is breathtaking, is why I half considered a passion wagon for a trip up there again. The area is too vast to have a single base to do day visits out.
The alternative would be being organised to have hotels booked and a strict itinerary, but that's not how we holiday.
