Thanks for the info folks,
Towing Weight - seems to depend where you look at, I have seen figures varying from 1450kgs to 1800kgs for a 3.0 elite estate.
I am not sure what my permitted towing weight is for my licence - I passed in '91 but am currently applying for my 6th renewal licence (medical issues) - I know I lost my 7.5ton permission in 2000, but wasn't aware of any limit on towing size.
Autofluid - Won't have to worry as have a manual box at present - would prefer an auto for towing though...
Speed - What is the permitted speed for a van - am I right in thinking 60 on a motorway and 50 on an A road?
Price, Make etc, all to be decided. Wondering whether to buy a reasonable old wreck to start off with and get used to it.
I have never actually towed a caravan before but have towed several different sized trailers including towing a twin wheel car trailer some years ago - remember it was a lot easier than the smaller ones, especially reversing.
I can imagine that the 3.0 engine would not really significantly notice a caravan behind it in terms of performance, probably lower running speeds wouldn't massively affect the economy too badly either (can't get much worse anyway).
Cheers
