I am no lightweight. But, if you want a pw that does not need a buffer tank, and you want to lift it in and out, to be honest you might throw out your back. I did a micro trailer build, it’s not any where near the setups of the big boys on this forum, but it makes me money without breaking my back. Let me find a link…Micro Trailer Build: 4GPM, 4,000PSI 3.5 x 4ft
Just once you get to the point of needing more than a consumer grade machine. Either figure out a fixed setup in the bed of your truck, or a small trailer to start. It is far better to invest in supply and pressure hose.
You will need the length at some point, and look a lot better pulling up to a job and just pulling out line.
