hi to anyone who's got an interest in this. I've towed the van this weekend, only an 80 mile round trip, but what a difference it was, it pulled well in 6th on the motorway, and pulled well in 3rd on the hills in the gower "if anyone knows the place". I did not keep it in 6th but used 5th as the fuel consumption went down in 5th, but the extra power was there if i needed it. I could have probably used 4th on the hills, but opted for 3rd, again, not to strain the engine, and for the fuel economy. So all in all everything has got the thumbs up. Mike
