Same here. Westfalia Columbus 641e. Really love the underfloor heating when skiing. And with 150W solar and 230Ah LiPO4 underseat battery we only use hook-up when in a campsite to do our laundry.We went from a Hymer B544 to a PVC Westfalia Columbus 6.36 long and like all Fiat Ducato vans the body was 2.05 wide.
With a 180HP engine we could go absolutely anywhere. We stayed with the Comfortmatic robotised auto box which was our third. We always used Adams Morey who know more than most about that box.
Good insulation underfloor heating and the ability to sleep 4 or even 5 people made it a winner.
Narrow lanes and mountain climbing up hairpin bends was for us much easier and more relaxed in the PVC than in the A class.
So for us a PVC - sadly now even shorter than before!
And the filler converts the two single beds in to a massive double. The underbed garage allows us to carry two sets of golf clubs, trolleys, and more and more.
