AVAN RAY Pop Top Caravan

Hello,

Does anyone have any experience with this van. I like the concept but am worried about the build quality as to wether it can handle corrugated roads etc. I enquiried with the retailer about a beefier suspension like Avan use on their campers but was told that Avan would not come at it. I am wondering why because it would make the RAY more appealing and is the only thing holding me back from a purchase.
