I like the convenience of buying a ready-made system but I'm unsure if the premium is worth paying. I'm interested in the omnivac in its own right but I'm thinking about a comprehensive van mounted system consisting of hot wfp, gutter vacuum, generator, pressure washer etc. I really wouldn't know where to start sourcing the components.
Does anyone know of such a system? If so could you send me some photographs and information as to whether it's DIY or ready-made. Is there a definitive guide to building your own comprehensive system?
