Thally

HI all I'm going out of my mind I've been towing my caravan (coachman highlander 550/5) for the last 4/5 years with a Mondeo estate 2.2 with no problems now it's time to change the car I'm struggling, I try to match the outfit and nearly every car is out
on the kerb weight, am I doing something wrong or have I been mismatche'd the past 5 years, I have a budget of around 16000 but everything I look at is either not right on the weight or just not right for me, some suggestions would be nice so I can get options.
Please any one replying with weight calculations please keep it simple as this is already baffling me

Cheers
