I moved about 1100 miles 3 years ago. I filled my COE flatbed up, a small utility trailer behind that; and then my dually pickup pulling my car trailer that was loaded with garage stuff at least 6000 lbs worth. That was about most of the heavy stuff from the garage. Not including lighter stuff the movers took, and not including any vehicles. I would say that I easily have over 12,000 lbs of just tools and car/house stuff I moved myself. Tools are very heavy and can be very bulky to box up or package for moving. I do not have any lathe or mill, just standard car stuff. I left a lot of my big stuff like several engines, trans, rearends, and big car parts back at my old house in storage. Still need to deal with that someday.
I drove 3 vehicles out total, and had 4 hauled by car hauler.
I have more **** now and I think I would do the OTR trailer rental plan now for all my garage stuff. Load it up and have someone else drive it to a new place.
No matter what, moving a big garage is a lot of work.
