Just found this post. First trip pulling a small caravan.
204ps DSG LWB full camper with Revo remap. MFD showing up to 22mpg on motorway run. I usually get 32-38mpg without.
Calculations show 26.9mpg on full tank. 5/8 pulling caravan. 3/8 commuting.
Annoyed I couldn’t find anyway to fill up to separate the two parts.
