You're not the first person with a low tire on base.
Ask an mp about their protocol. They likely just waive the truck through the gate and give them directions.
I'm going to suggest a compressor. They're light and cheap and will take your tire from 38 to 82psi in ten minutes. They'll take you from 77 to 82psi in about three minutes.
Almost any 12v or 110v little compressor will do fine.
I prefer this one.

Because it uses the same batteries as 150 other ryobi tools AND you hook it to your tire, set the pressure you want, hit a button and walk away. It turns itself off when the pressure reaches what you told it to. No cords to drag around, no generator to turn on so you'll have 110v. Nothing squirelly, just a tire filled. I'm thinking this compressor and battery weighs in at between two and three pounds. It's the size of a five pound bag of flour, but weighs much less.
If you had one now, your low tire wouldn't have been a thing.
Home depot carries the compressor and battery.
I carry one.
