We just picked up a 150 DSG and the engine pulls very well. The auto box is great and makes it relaxing to drive. We bought from VW Liverpool. Very good service and advice on the options. Good luck with it all. You will love it whatever you go for!
Born and raised in Cheshire (and /or Merseyside, depending on when and where the boundaries were moved) and have a T6 204 DSG 4 Motion having never owned or driven a camper before.
Good luck and welcome to the forum.
You should get plenty of info and advice on here.
