I had not looked through this thread before. That is a bummer to read about the build and Wayne. I remember the build thread, even commenting in it and I liked Wayne on the forum years back.
I am sure it is history for you now but the thread and story brought back memories for me of a very similar experience I had back in the early 2000's. I had a 712m 6x6 Pinzgauer that was in need of a lot of work. On the Pinz forum was a guy, Dennis, who owned Linden Engineering in Colorado. I was in Wyoming so he was kind of close. He seemed like a nice British chap, contributing on the forums, seemed very knowledgeable and he was well traveled and supposedly had worked on a lot of Euro trucks most his life like the MAN, Pinz, Volvo's and others. So I booked a $18+k build with him and took him my truck. Five months later when I got my truck back it was the 4th of July so I jumped in it and went camping. Got it stuck one night, new winched burned up super fast trying to get it out. Clutch froze up the next morning. So I towed it home and started tearing into it. Come to find out many things I paid for like all new brakes on the truck we not done, there wasn't even new parts anywhere in the brakes and I had paid for new gear from master cylinder to brake springs.
I called up Dennis who gave me the run around and a fat line of BS and blamed it on his employees. He continued this way for some time (perhaps hoping I would just go away) until I went public on the Pinz forum as well as threaten to turn him in for fraud. Within a week of me going this route he had come to my shop in Wyoming with every part I request in the build that was not right. He then himself, spent a week installing all the stuff in my truck while I supervised. He regained a lot of my respect for this, as much as he could after many months of BS. And since I had went public with my negative experience I certainly gave him props on the Pinz forum for manning up and making things right. I actually even bought a body off him after this so we did some more business although he never touched a truck of mine again. I did hear from others during my experience with Dennis and for a few years after that they had very negative experiences as well.
I only did on build after this that I paid for before going the route of doing all my own work.
I like your Troopy!
Cheers
