Look up draining a trailer. Not sure how fellow did mine. Put glycol in
system and hot water tank after pushing or sucking out water.

Glycol antifreezes are toxic. Google it. I use alcohol based RV
antifreezes. The hot water tank needs no antifreeze if you open the valves
and let it drain completely.

Propylene glycol is non toxic- commonly sold as "plumbing antifreeze"
