saw a glimpse of a dolly/stand on one of the vids here, what do you call it Samurai was your vid. Tilt it back to get access to bottom.
I usually have them full of water lol.
So how do yall get the water out?
Pump to drain
Then there is always the remaining water, or you need to clean a filter on front load that is nasty, how do you avoid the mess.
