I just bought a used truck bed that use to be Terminix. Came with what appears to be a 50 gallon spray rig with a gas engine and hose reel all in good shape and a Utility cap with doors to open and access it. I am pretty sure you can spray herbicides with the same unit after flushing? I have no interest in it, what do you think it would be worth, I dont want the sprayer or the cap. Email me if you are interested in it.
