I'd like to be able to "air down & up" to go on sand. We recently visited Oregon Inlet Campground and the sign posted at the beach entrance, shown below, requires one to air down to <20psi. The posts in this forum say airing down is essential; so far so good. I'd like to be able to air back up quickly.
I'm a viair fan so I was wondering is anyone had experience with the top of the line Viair 450P? I like it for the extra hose length and other accessories that come with it that I can use with our travel trailer. Plus the duty cycle of Continuous Use @ 72ºF & 100 PSI: Approx. 1 Hour.

The fill rates are listed here for larger tires and they seem like they're more than adequate for my tires.
| 35" x 12.5" R15 | FILL RATE |
|---|
| 37" x 12.5" R15 | FILL RATE |
|---|
| 0 to 40 PSI | 7 min. 41 sec. (+/- 15 sec.) |
| 10 to 40 PSI | 5 min. 54 sec. (+/- 15 sec.) |
| 0 to 40 PSI | 8 min. 50 sec. (+/- 15 sec.) |
| 10 to 40 PSI | 6 min 41 sec. (+/- 15 sec.) |

Remind me what tire size you run again?
A number of people in my group run the 450P. Old faithful, solid performance, and a premium pump that will always deliver. For something less than a 35" tire, great pump to get. For a 35+ tire, and if going from super low to high inflation pressures like towing, say 15-45PSI, it can get tedious. At 6 min per tire, x4, and it's 30+ plus minutes considering the logistics of pulling the pump out, hooking to battery, connecting to tire, moving from each tire (octopus helps)... 30 minutes isn't bad, but it's enough time where it might be a factor in not airing down at all or low enough.
Some might say why the rush. Depends on use case and how one uses it, but there are days off-roading when transitioning on freeways between segments, where having to air down/up 2-3 times a day, makes a fast pump worth it.
If you have a mild tire size, and team red, the Milwaukee M18 is a great inflator. Not as fast as the 450P, but it's self contained/powered. Auto shutoff. The ease of use can make it a great pump especially when considering the trailer.
There's some epically fast new kids on the block too. Something like the
MOORFlate FiveSix or even TenSix. Requires octopuses as they're that fast and too limited by the tiny Schrader Valves. Many re-branded and variations of these pumps on the market all over the place, though not all will exactly the same or of the same quality.
