Hello all, I finally made an account but ive been lurking these forums for a awhile. I live in west Texas where the heart of the oil boom in Texas is. I worked Frac for almost 2 years and had enough of working 160+ hours a week and with the oil feild slowing i decided to get out and use some of the money i have saved up to start my own mobile wash. I already have a contract to wash 4 18 wheelers a week but mostly wanna focus on cars but ill do what i have to, to get started. As of now I have a truck a trailer, 330 gallon water tank that will be filled with R/O water, and a ONE Plus Steam Cleaner by Dupray . I need help picking a pressure washer and if I should run a tool like the Tornado, and what generator. I have about 1,800 dollars left that i wanted to spend. I also need to purchase supplies like brushes and chemicals. If yall had 1800 left to spend what route and tools would you buy conisdering you will be washing 18 wheelers (water haulers) so i know i need a strong PSI pressure wahser i found a OneWash by Generac that you can adjust PSI (2000-3100) anyways what are yall ideas?
