Hi Happy Camper,
What if I may ask is your in depth interest in the Jurgens factory? I personally have had one or more of these caravans over the years with never a complaint uther that complaining to a dealer about poor service, ie changing a wheel bearing in the dirt of their backyard Comet Caravans, Echo 4 x 4 probably the worst service imaginable to me, and so you can go on and on. Just tick all the boxes and then draw your conclusions, Jurgens will surely come out on top. Componentry of Caravans and motor vehicles these days are all modular so the best chassis in town Al-CO that applies to most caravans carries their warranty.
Just a comment from a happy camper starting with a 13ft Jurgens and today a Jurgens Elegance over a 50 year period.
