I am taking my caravan in this morning for its first service, and it will be the first time that I have towed with my CR-V. It's a journey of about twenty-five miles so I should get some estimate of fuel consumption when towing. I'll report later. - - - Updated - - - I took my caravan in this morning and no problem towing. My 'van is 1500kg and the CR-V towed it with ease. I stuck rigidly to the speed limits, and no more than 55mph on the M58 and M6. Upon arrival the computer readout gave an average consumption of 35.6mpg. I don't know how accurate the trip computer is, but if the figure is right then I'm well pleased. I won't really know until I go away in the caravan and can check on the full to full method.
