but i dont want to trail a hose pipe everywhere, if i have a backpack, its lift and go, lifting 20k isnt hard work do it all day will be double 12' wooden a frame above my head, and as for filling, it wont take long compared to not doing the job at all because i cant reach certain windows, getting a tank just seems to defeat the simplicity of the desire, unless you can suggest a tank i can clever put into me astra estate
