Jumping back in the saddle!

Well decided to pick up the polisher + microfiber towel and go back into detailing + wash. This time I will be going mobile wash; leaning into gas powered pressure washer. Anyone can share an ideal set up, I do plan on going gas powered pressure washer, 60 gallon tank, and have a generator to get some electrical power for polishing + vacuum. I am leaning a build in where I would not need to take down my tools and load them up on the weekends. I've seen set ups where the pressure washer is just the engine whiteout the wheeler, if anyone can help me where I get that; thanks.
