This reminds me of years ago when we had a Cav CD (the one with the high top gear for economic cruising) Well, we got ourselves a nice Mardon Classique 4-berth and the Cav wouldn't pull the skin of a rice pudding with the 'van on. So we immediately swapped it for a Cav SRI which had the top gear the same ratio as the fourth on the CD - what a difference! Pulled it like a train - kept going over the speed limit and still very reasonable MPG

I have a 2003 Vauxhall Vectra 1.8i and tow an Eldiss Shamal with a mptw of 1200kg.
I have recently been getting 26mpg whilst towing and think that it is a bit low.
I noticed that it is ok when I get upto speed but hates hills (always changing down)
I love the car but should have got a 1.9td just for the extra poke.
The Vectra 1.8 is going to have its work cut out pulling 1.2 tons so if your getting 26 mpg you doing not bad , as you say the 1.9 cdti vectra diesel would probably be more economical but to expect more mpg may no be achievable
My pug 406 2.0l HDI 110 does 32 to 33 towing Ranger 510/4 1200kg.
I find its 28 or so towing home from cornwall with all the hills & climbs to 33 between Exeter & Bristol. Must say the diesels go up hills well, glad I haven't got a petrol.
I have just bought an Audi A6 2.7 diesel and manage 45-50mpg when solo and carefull, but got 28mpg towing to Yorkshire this week. Have to say though what an engine it pulls harder with the van behind than alot of solo cars!
When i was towing I tried to keep my revs below 3000 when accelerating thinking that It may be the key to better fuel economy. Am I driving ok or should I be giving it more revs?
------------- Life is like a box of chocolates. You never know what's next.
The specific fuel consumption of any car is best at the revs where maximum torque occurs (3400 or 3800 rpm on the Vauxhall 1.8 16v) BUT reducing speed, acceleration and braking will improve consumption far more.
On any petrol-engined car you'll need to use the gearbox, that's what it's for. For cruising, top gear is best but you'll perhaps need to be ready to drop a gear or two for accelerating and hills.
