It will be the same except a hand written TR (tourist visa) Mine is the same except it has a hand written DTV and I get 180 days. Always best to check the dates in the stamp before leaving as it is difficult and time consuming to get mistakes rectified. Every new entry under a METV will require a fresh TM30 even if you stay at the same address. This will only be an issue if you plan to extend by 30 days. If you don't plan an extension then the TM30 is irrelevant. If you leave and re-enter at the very end of your 6 month expiry date you can get almost 9 months stay from an METV.
Becoming tax resident does not mean you have a tax liability in Thailand. If you bring untaxed earnings onshore to a Thai bank account, you have a Thai job, or you have investments in Thailand then you have a tax liability here. If none of those apply just enjoy your holiday.
