Thanks Amdram
Decision made after further research and test drive at dealers very smooth driving an auto , definitely a more enjoyable experience on a long drive when towing , so looking forward to getting out soon
Just a quick thought, You tell us the Sorento will be a new tow car for you, and as many have pointed out it has a very good reputation I'm sure it will do well for you.
I note your caravans has an MTPLM of 1500kg, and the Kia should manage that very well. However the Kia is already a heavy vehicle, and I know most models have a kerbweight starting at close to 2000kg which means its GVW figure will certainly exceed 2000kg. This will mean the combined MAM of your outfit will be greater than 3500kg, and thus your driving licence must have cat BE on it for you to drive it legally.
If you passed your test prior to 1997 you will be fine. But if you passed after in 1970 or later the basic licence only has Cat B which limits you to a car and braked caravan with a "combined MAM not exceeding 3500kg". (i.e. Cars MAM or GVW + Caravans MAM or MTPLM<=3500kg)
MAM stands for the Maximum Authorised Mass and uses weight limits not measured weights.
If you only have Cat B you will need to take the BE extension test.
