hello guys thanks for all the kind words... to answer johns question i plan on using this setup for my own use.. my intention is to do truck washing with it.. i have soooooo many man hours in building it and so much $$$$$ invested as well.. as far as a figure i havent even added it up officially.. but i would say upwards of 40k invested in the box alone ... not including the truck... . i am trying to complete this rig but my final metal fabrication is not completed... i designed this setup to be very easy to work from the ground .. where everything is right at your fingertips... my remote system controls the one machine from a 1/4 mile away .. not that its needed but its nice to have... the vac system is my design and i had thoughts on building these units on a big scale , but 2 much is on my plate to finish this one.. so far the testing that has been done works unbelievable .. i am very pleased .... i am not good with the computer at all but a friend of mine is so we are going to put something together shortly... everyone who see it in person says i should build these on a mass produced scale but i would need a facility to do it in ... in the near future i am going to bring it to a round table event.... thanks again guys.. if i can be of any help to anyone on this board feel free to give me a shout
