Belly dump switches

Hello all. This is the first thread I've started on this forum.
I used to haul end dumps but have been OTR for a while now. I plan on setting up my truck for double belly dumps, mainly because I can't afford to put a wet kit on it. I'm in the Las Vegas, NV area, and it would be great to find someone near me that would let me take a look at their truck so I can reverse engineer the switches and layout, take a bunch of pics, and so on. If anyone is available, I'll buy the beer. Barring that, if anyone has the pics and information I could use it would be very much appreciated. Any info is better than none. I know I could do it a lot cheaper that the $2500 TruckPro told me it would cost.
