Safest towing vehicle

Hi everyone, new to the forum but should be a regular visitor from now on. Wife and I have just ordered a 20'6'' Opal vacationer 206 to be delivered in June. With a tare of 2650 kg, what towing vehicle has proven best and safest to tow this type of van? We cannot afford to buy a "brand new Cruiser" but what would be economical alternative that you guys have tried and tested? We are working on a 3,000 kg tow for max safety.
Hope you can help,
