TM30 and residence certificate?

[Dezmo]

Asking clarification on obtaining a residence certificate (I want to buy a motorbike).

My understanding is that I need the residence certificate to register the bike once purchased (and maybe actually buy it).

I assume my TM30 need to be filed, and I may need a paper copy to bring with me.  I recall the TM30 may have a timeframe on it (e.g., days in hotel).    If so, I assume I need to bring in the TM30 on the day[s] that's listed on it.... that is, if I go in after the TM30 end date, it may not be accepted?  (I just may be changing lodging and not yet checked into the next hotel, etc.).

I do have a 1-year extension on my Non Imm O Visa (expires Jan 21 but I'll be in Thailand before that) so I did have a TM30 when I got my extension (though my gf may have put an end date that has passed... so not sure that matters).       So maybe I can easily get the residence certificate without a new TM30?

Thanks.

Which Immigration office, and why a hotel rather than stay with the girlfriend?

What address is on your driving licence?

Nonthaburi. I sometimes stay at AirBnb (some do not do a TM30).  Driver license is in USA (but have IDP). My understanding is that I do not need a Thai license.
