Why doesn’t Phoenix use an aluminium frame on their Heavy-Duty models?
We have used aluminium frames in the past and we still use aluminium framing for certain non-structural applications. Phoenix has traveled the hard road for many years as a Caravan Repairer and is well conversant with the vagaries of accumulated stress, or metal fatigue that is likely to become evident in a hard used caravan. As a result of this experience Phoenix Engineers developed the concept of Progressive Stress Absorption. This concept takes into account the fact that no matter how robustly a caravan may be built it is still subject to racking and longitudinal stress generated by road movement. This stress must inevitably be transmitted into the body of the van through the chassis and suspension. The principle of this unique Phoenix design requires that the structure of the caravan must encompass an ability to progressively absorb and dissipate this stress. This is achieved through the use of an absorptive rot resistant timber frame and an ingenious slip mechanism that allows the
