do you have any more pics, tubework, ect? Depending i would go 4 to 5k for the rig and 1200 to 1500 for the trailer. I know that sounds low, especially for the work you got into it, but it's easy to find a cheep rig to build and most people who are looking for completed rigs are looking for a deal. The trailer (even though only 1 use can) can be found all day long for 1500.00. Good luck selling it and i hope you get what it is worth as opposed to the prices i suggested!
