I also own a caravan although I don't own an Omega i have a V6 vectra - which tow's great, on makes and models - I have an Lunar - they are known for lightwieght vans - mine is around 17.5ft 5 berth but is only 1240 kg's well within the 85%.
I have towed vans for a good few years on and off - it can be quite a challenge at first but as long as your car is in good order you shouldn't have much of a problem. I would advise you join the caravan club - you can get a lot of advice from them plus they do caravan towing courses .
I have had old ones - the trouble is they look ok until you get on a site and you look like the Gypo lol, no they are usually have something wrong with them!!! just like old cars.
i bought a new one last year from a show - got a huge discount there too - I would recomend it, but don't buy a small one, they look huge until you go away in them.
Best to borrow / higher one before you commit to buy!!!!!
as for stabilisers - i use an alco one - it replaces the hitch on the caravan and uses brake pads on the tow hitch - by far the best type to use.
And as for cheap holiday - its not these days, your car will feel like a vauxhall Viva when towing but will drink juice like a V12 jag.
Following on from the Caravan Tyre warning earlier, I am thinking of getting a caravan at some stage - not a new one by any means, but fancy something to tame the 3.0 on the road..
Any recommendations for an ideal sort of size of van/weight etc for the Omega? Ideally I would prefer a larger van 3/4/5 berth just for space and comfort, but would appreciate any pointers or advice from our existing caravanning members to look out for should I finally decide to take the plunge.
Mine is a 3.0 elite estate on a P - so not new but has typical features of the specification, obvious thing I would only drive it with an anti-snake device as have seen too many vans on their side for various reasons.
Any other mods necessary for the meega or other things I should be aware of with the meega towing?
Cheers for any advice
Steve
