The truck wash is 100 20 ft box trucks lined up in an open lot, the drivers park all over the lot so I have to move from area to area to clean about 5 to 10 trucks at a time. Inject soap then scrub if necessary then rinse, move to next group. I hook up 4 or 5- 100 ft hoses to clean as the lot is quite large probably 1000ft by 500 ft.
Rest of time I clean houses, decks, concrete pads and the rest of stuff you can imagine.
Been there and done that as well. We used to wash a lot of car dealerships and some big rig outfits, not to mention Casino shuttle buses, so at times we would double up on pressure lines to get 100 plus ft. The longer length was necessary in those instances.
The owner of the auction was big into horses, so I can say for sure, the worst thing we had to do was pressure out his horse trailers. Ha, I don't think I will ever miss that....
