Well I'm back, finally I got things working my way. Durned if that pickup that was too light didn't haul the load that was too heavy, imagine that. I think 3,000# is not too heavy for 2-3500# axles, but I suppose U-Haul is right, 3,000# does exceed 7,000#, I'm just glad I wasn't their mathematics instructor. I suppose sometimes it is better to depend on yourself.
I would be cautious on using computer media to preserve historic data, there is just no media designed for that purpose. Floppies are subject to magnetic forces, CD's are better but research shows they can lose data as they age or are damaged, hard drives are limited to aging, about the best thing out there for long term is tape backups, but once again they are subject to magnetic forces. Perhaps one day silicons chip technology will make long term storage feasible, but that is not wide spread technology, and it is still being developed. About the only proven technology we have is the old paper and ink, it is proven to date back to Egyptian times. Even though, nothing made by man is perfect.
Take care!!
