I'm now onto eating the next bit of my elephant - also known as the Fiat Ducato Knaus motorhome. Years of wet wind blowing underneath it has left its mark. The front jacking point mount has partly disintegrated, and I will be welding in new steel, continious welded. The offside step has a rust patch which I've cut out and made a repair patch. So far I've punched a hole every inch or so and plug welded it. My question is, do I need to continuous weld this? The van has a chassis front to back, the step isn't structural and is otherwise good.
