Questions About the 21AXP22 Color CRT

[TVBeeGee]

I'm the new owner of a CTC-5 that still has a working 21AXP22. I need to transport the TV about 30 miles. One leg of the cabinet is cracked such that it would be unsafe to transport with full weight, so I plan to remove the chassis, tuner and deflection coils to reduce the weight before transport.

My question is:
Should I also risk removing the CRT and packing it separately, or is it less risky for the metal-to-glass vacuum seal to leave the CRT in the cabinet?

Considerations:
The metal CRT only weighs about 28 pounds. The cabinet weighs far more, so the weight savings by removing the CRT might not be that significant. Plus, keeping the CRT in the cabinet would allow it to remain horizontal, which might guard against cathode material falling into the shadow mask.

On the other hand, the leg repair may require turning the cabinet on its side or even upside down, which would place the CRT's metal-to-glass bond in an unusual attitude. In the process of fixing the cabinet, the CRT might be jarred more than if gently transferred into a padded carton first.

Just how fragile is the metal-to-glass bond in these tubes? Are they as bad as the 15GP22? Is a working 21AXP22 a "don't touch and pray constantly" zone?
