I haven't slowed down wanding really,,,,,,,,,i did at first but there doesn't seem to be a need to unless it's really nasty or soapy
M-5 has 2 cords
I have a kero heater in my van
I've been using the Mytee hot box in line heater quite a bit and it works quite well so that's 3 cords
pump is 5/600 psi so I don't know about the tile but I guess I could add a water hog
