That sounds like quite the adventure.
So what did you do with your truck today?

I have a sister and a bunch of niece's and nephew's in Fruitland. A cousin who's not far from Cheyenne. You're doing what would be my family tour. Admirable road trip.

Funny you should mention Fernley. I got a kind of job offer from there Wednesday. He that he was joking around, but the way that he said it, I kind of wonder if he's having trouble finding and/or keeping help. I wouldn't take it anyway.
Depends on where you have your vacuum tapped at. If you have a vac canister, the check valve retains vacuum. If you tapped into the vacuum manifold, when you key off it instantly goes away. The brake booster keeps some vacuum because it has a check valve on it.

Mine does. I have it tapped in around the same spot. I'll guess that it probably takes maybe 5 minutes. I haven't timed it. I had one pump that it might have taken a minute to drop to 0 after the engine was shut off. That one would only build a max of 17" on my gauge, but that was enough to work the power brakes just fine. My gauge is a cheap one and it may not be really accurate. It could read a few inches off.

I think I might have found the maximum capability of the stock mechanical lift pump… I have 5 psi of fuel pressure at idle but have about a quarter to half inch of vacuum when I really get on it in higher RPMs. That’s measured at the filter head.
I found this out when I turned up my pump again (Moose Junior, 90cc?). I put 3 flats to it a while back, seemed barely better. So I put another 3 to it today. Noticed zero difference at all. Maybe a touch more smoke before it lit off. Timing set at 5* currently.
I plan on putting a Walbro FRB-13 on sometime this week, and deleting the mechanical pump. That might not quite cut it, but I’ll give it a try.
I called the folks at Walbro, it seems that I can stack the pumps if needed. I might wind up doing that, but I’ll just start with one pump. They can be pushed or pulled through, so having a second pump on a switch for when you need it is an option. They are auto regulating pumps, only cycle as needed. If it holds at the desired pressure then it will just stop pumping until it is out of the range it seeks, then it resumes. I think it can bleed back through itself but it’s self priming anyways so it will probably work great. Should be nice for priming a new fuel filter. The pump has an 18,000 hour service life, and is made in the USA.
Hopefully I have better luck than with the Holley pumps that I kept going through in my 86.
