The diesel engined BEAST truck (2003, Ford 350, Flatbed) pulls the darkroom trailer easily. Sometimes I need to check to see if the trailer is still there. I also love the truck as a raised shooting location and as a big table for all the big ass trays I use.
Love the new 4mm glass as well. I will need to buy more, it is expensive, but I think will make for better Ambrotypes. More depth looking through the 4mm glass and most importantly, less breakage. I also just like the heavy feel to it One annoying thing is I need to tape the back of the Chamonix wet plate holders when using 4mm, to prevent light leaks and fogging.
Hope to go out 2 times next week and try my hand at 24x24 inch plates. Short of trays thou, need to remedy that.
