A convertible ladder-carrier vehicle assembly includes a pair of parallel tubing elements connected by at least four transverse tubing elements. A second pair of tubing elements are positioned slidably within the first pair. Both pairs of tubing elements have aligned apertures. At least one resilient member having a hook element at each end is secured between the first pair of tubing elements detachably within the aligned apertures of the first and second pairs to thereby maintain the second pair of tubing elements in fixed relation to the second pair. A wheel assembly is detachably connected to each side of the first pair of tubing elements, journalled in intermediate transverse tubing elements.
