Your posts are always interesting to me and I appreciate the details and pictures.
It looks like we are at opposite ends of the spectrum since you are building a custom rig and dealing with all the associated pitfalls. To a degree, you and others are paving the way for future 4500 and 5500 development which I consider a good thing.
I have been building, breaking, and repairing rigs since the early 90s and I decided to go in a different direction. The only labor required for my AEV Prospector and FWC combo has been me vocalizing my bank account information over a phone two years ago.
My reward has been a quick build on a stable platform, and thousands of miles on the trails. And I carry zero tools.
Best of luck and keep up your reporting and pictures - I always enjoy them.
