The reason you probably didn't get a reply earlier is that the Regent is not as widely owned as some more mainstream models. In fact I have never seen a review in any of the motorhome magazines.
I own a La Strada Regent and it is absolutely superb. The build quality is superior to any of the UK motorhomes I have owned. The Mercedes Sprinter engine ensures you have the acceleration and power when needed and driving it is an absolute pleasure.The drop down queen size bed is one of the most comfortable beds I have slept on. An excellent end bathroom with a separate shower unit and excellent mirror for shaving or in the ladies case putting on make up. Both front seats swivel and the positioning of the table suits us fineIn short I cannot say a bad word about the vehicle
