Just done a 2000 mile round trip to the Vendee in France with 5 young people and the trailer.
The trailer isn't aerodynamic and I managed 22mpg at 60 - 19.5 mpg at 70.
Fortunately diesel is cheap in France.)
The Bammer was a pleasure to drive and uncramped with 7 up. Good for towing - the trailer was very very stable.
Redface bit, I blew the brake lights on the car connecting the trailer up in the dark for the return journey home. I couldn't find the offending fuse (although I went straight to it at home..). Brake light emulation with sidelights when the Gendarmerie were about.
Then, on the M11, a motorcyclist suggested I had a
problem and when I pulled over, I found that the trailer indicated left when the car indicated right....
You wouldn't think the trailer plug would go in upside-down, would you?
Because the brakelight fuse blew, the glowplug light was flashing. Because of that, no cruise control on the return trip.....
