I moved my 4 post on my trailer 227 miles, installed it myself (when I was in my lates 60's) and would do again. You'll never sell it anywhere near the cost to replace it today.
Two years ago 9100sq ft cost me $30k in the middle of NH. They added two truckloads of base to what I already had, rolled it out on day one and paved on day two.
Are you sure getting inside the property line is enough? Can't speak about TN, but everyplace I ever lived there was always a setback within the property line before you could build. Also, are you on good terms with your neighbor? If my neighbor came to me with an issue like this I would...
I have a standing seam metal roof on my RV garage/workshop with a 7/12 pitch. Pretty good snow fall (middle of NH) and it always slides off once the sun comes out. I don't think I would do anything less.
I don't know if they still have the same quality, but I've had a Bend Pak BP1 (14k, extra wide and long) for 25 years with zero issues. I think I paid around $2500 delivered in 2001 so I consider that money well spent, especially now that I'm old.
I have a 67 mustang and was planning on welding subframe connectors from the front to rear subframes. I jacked up the car around 18" and stacked blocks under the tires. I lowered the jack and everything was secured, but I noticed the tires were not centered on the blocks. That really didn't...

My previous house had a lot of cathedral ceilings and that's exactly the way the drywall was installed, over 1" of foil backed foam board, which was screwed to the rafters with fiberglass between the rafters. We lived there 27 years and had no issues in a harsh New England climate.
I moved mine (older BendPak BP-12, 12k lb four post lift) using my 16' car trailer. Since disassembly/reassembly is not that difficult I never consider moving it as one piece.
Yes, I've used them for both small motors (2hp air compressor and table saw) as well as automobile and motorhome alternators. This was in CT (2016 time frame when I lived there) and there were a couple of shops in the area.
