Calm down, Don! I didn't actually assert anything at all in my post. I simply requested information! Here's what I said: Now Don, what do you have, and what does it do when you're hauling your little mobile home round the country? Huh? Naturally, I assume you own two cars, one behemoth for the annual fortnight of caravan-tugging and the other with an elastic band that gets you 80 to the gallon the rest of the time. Well?

Here's another enquiry (feel free to respond, not respond, or simply have another rant!) - you said: Pulling the caravan on motorways at 60mph (the legal limit) 35mpg using the Rover's amazingly economical cruise control.

Well 35mpg is a bit naff these days anyway, Don, not exactement environmentally-friendly, but even so you are hardly giving us the full yarn here. A nice, steady speed on a road with only gentle gradients with your cruise control on gets you 35mpg. Now I assume you don't spend your caravan hols in motorway service area car parks, therefore you will be driving considerable distances, I assume, on twistier roads, accelerating and decelerating, lugging up long and short and steep and not-so-steep hills, stopping and starting, slowing for roundabouts and speeding up again, getting stuck behind milk tankers on big hills, forever ramming it into third... bet that lot eats into your 35mpg somewhat! :-)
