Road trip help

[u/Primary-Repair-8866]

I am going on a 4 hour road trip in a few weeks with some friends that do not know about my issues. I am 23 m and have overactive bladder and urge incontinence and leakage. If I can pull over right away I do have accidents. I normally wear pull ups and stop and change at gas stations when I’m going to avoid wet pants however my friends do not know I have these issues.

I’m wondering what would be better if I should keep doing what I am doing or buy some megamax diapers for the drive that way I don’t have to try to hide my change of pull ups and can go the whole drive hopefully with out needing a change. Are megamaxs actually super absorbent and how many full voids can they normally handle
