Thanks to all who replied.
In no particular order
It is the A class I 7820-2
Full winter insulation
Alde heat exchanger
Increased battery capacity and extra leisure battery
120w solar - waiting to see how that copes and what room is available on roof before looking to increase.
No air suspension, again want to run it first and see how it copes but as others have done could be retro fitted. It was an expensive option!
Left hand drive
As it has the rear lounge the garage isn't full height although the demo model had bike tracks fitted but I think showed with front wheel removed?
The front drop down is the main bed and will definitely be used as we don't want to be making up a bed in the huge rear lounge. Plus it means that other person can stay up while partner has an early one
Due to its size I think there will be ample storage for 2 - although seeing OH pack for a weekend it may be an education exercise!
SOG - not spec' but on my list
Refillable gas - likewise
Kitchen vent/extractor, air con to cab, automatic gearbox all included.
Size - was the biggest question mark in my mind, BUT, as far as I can see, the only consideration that everyone on the forum agrees with is, LAYOUT, LAYOUT, LAYOUT, is the single most importsnt factor in getting satisfaction. I'm pretty confident we have chosen correctly in this respect.
I have driven many types of vehicles over the years and size hasn't bothered me so far, hired a large motorhome last year to try out @ 7.5 metres around parts of NC500 and found no issues. I've read @Northernraider exploits and as he says there are very few places you can't take a larger MH.
Hopefully that will not come back and bite me on the backside once we start and travel. I take the attitude that the more remote places still get delivery vans, refuse wagons and the like, in Spain you see coaches up and down the mountain roads without any serious issues so fingers crossed
I hope you dont regret having a smaller garage when you want a scooter, but then again I prefer to come into the lounge at the front, then the kitchen, then the bedroom.
