What should I expect when re-entering Thailand via land with a DTV visa, specifically regarding proof of funds?

I have bad experience with Padang Besar, I was on visa exempt there early 2024 and after an afternoon shopping in Padang Besar with my Thai girlfriend, Thai IO did not let me in, he told me same day entry was not possible at this checkpoint.

Allthough such a rule does not exist, there is nothing you can do about that.

The only thing we could do to gat back t our car we left at the Thai side of the border, was getting our Malaysian stamp void, get back into Malaysia, get a taxi in Malaysia to the nearest border crossing that would let us in, then get a taxi back to the Pedang Besar border crossing in Thailand.

This was all before DTV existed, but for me never Pedang Besar anymore.

I never had problems with the Sadao border crossing not too far from Padang Besar

No idea about that border but you can definitely be asked to show funds although its not common, more likely you can be asked to show cash of 20k baht or equivalent (not in any sort of account, actual cash)

Nobody reporting that they have to prove the 500k upon entry.

There shouldn’t be any issues entering by land air or sea. You have a valid visa.

That said some borders may have “special” requirements. State the border you are going to use and others with experience of that border may be able to advise.
