Hello, we are new to caravaning. I have a couple of questions if you have time, appreciate your expertise. Does anyone have a Coronet van, or heard anything really negative on these. Looking at a poptop due to height limitations. As we are new to caravaning, would you suggest staying16 feet or below in length? Have towed boats previously. We have a VW Touareg and would like to hear from any owners who are towing vans with these. Thanks for having this to ask. Cheers
