A Honda  GX 390 will not run a 21 lpm Pump.  A direct drive pump would be a better option.

Would I use a ramp to get a wheeled pressure washer into and out of the van? As they weigh 80kg+, whats the usual setting up process?

Plus if you have a bigger pump and therefore have a return to tank hose, what do you do if you have the washer out of the van away from the tank in the van.  Or would you use a temporary water tank such as wheelie bin or barrel and have it near the machine?

I lift my machine in and out the van...but I'm not doing it day I day out.

If you go down the portable route then you would use a wheely bin or similar.

You can use a ramp I used to tie it to my bellend and swing it out.... but i’m From up north.😉
