Replacement of hot water tank

[Nursingpat]

Hi all,
My cold canadian winter has played a factor in a massive crack in my Wilderness trailer. I would appreciate insight whether it be easiest to replace only the tank, or would you recommend the replacement of the whole hot water tank and attached wiring/panel? Suggestions appreciated please.
It is a 6g electrical/Propane combo.

If you can get the whole assembly, I would do that. Then strip everything off the old one before trashing it.
