I use a Ford Ranger 3.0 TDCI to pull our Bailey Auvergne.When pulling we get about 27-30 mpg .But the best thing is the amount of stuff we can take , being a pick up with covered back it will carry upto 1 ton and pull 3 ton so i don't really know the caravan is there.Also optional 4 wheel drive to get us out of any muddy fields.
