I have the full package in including the generator. I keep it all in a small trailer (enclosed) as the gennie is a real lump. Not easy to move by yourself or even with two of you. With the poles, generator, Omnivac, extension leads, tools etc it used to take up all of my van. (I have a Citroen Dispatch LWB) It made window cleaning difficult (wfp) just because the van was overloaded. A lot of customers have gutter and windows done on the same visit or fascias etc, so I opted for a trailer. The trailer is soley used for gutter cleaning and life is much much easier now
Without the gennie it would fit in your van but with it you would struggle
assuming you have a small wfp tank of course
