Air compressor recommendation?
I never thought I'd bother with air compressors, but after arriving at a 4x4 parking lot for a hike and seeing a truck with a flat tire... well, time to revisit!
I am NOT an "offroader", almost entirely off-road is just up FSRs of varying degrees of quality.
I was originally thinking of simply buying a portable air compressor, but am almost positive I would forget it the one time I actually needed/wanted it, so go figure.
Is there a good budget option that easily mounts under the hood of the 4runner (have a 2020)? How long would it take to re-fill from, say, 20 to 35psi? So far, I have never gone up a FSR with someone who airs down... everyone just runs as-is I guess.

You should air down to 20lbs for a more comfortable ride on FSR but If you are not airing down for offroading then you don't need a mounted unit. For emergencies you can pick up a viair 88p or a smitty built etc for around 100 bucks from amazon or others. They come in a bag and fit in the back cubby holes. if you want more info, here is one of the numerous threads on this forum alone for a mounted unit.

I use the Viair 88p. I air down to ~15 and back up to ~34. It is not super quick, but for the price it works just fine. My brother uses the same compressor with his '18 JL on 285's

I have a Viar 400P and 88p. The 88p is perfect for emergency use, or light trail use if that all you want to spend.
My only gripe with the 88p is that I don't like the fixed air hose.

How much quicker is the 400p than the 88p?

I recently got the Smittybilt 2781 for use on the trails. I don’t plan to hard mount it under the hood at the moment because I like the portability of it.
From some reading I’ve done the 2781 seems like a better option for under the hood than the 2780, but again that could be all opinion.
The 2781 is capable of airing up all 4 tires at once, again from many reviews I’ve seen. So that’s a plus for me if I make a 4 tire harness for it and air up all of them to the exact same psi.

Almost twice as fast... higher the PSI goes, the better the 400p does as well.
I can fill up all my tires from 15 PSI to 32 PSI well before hitting any duty cycle limits, which is why I went with the 400p over the 450p, which is slower, but a 100% duty cycle pump.

The 2781 is approx twice the size and weight though, right?
Trying to imagine just how... portable these are to move in/out of car vs something that might be permanently mounted under the hood even if used infrequently...

Ya it’s heavier but I’d not call it “heavy” per say? I wheel usually once maybe twice a week in mine so taking it out a couple times a week isn’t a huge deal for me. I do like it’s ability to be mounted under the hood too though. I’m sure down the road that’ll be the plan.
I like that it’s a much stronger compressor with double the CFM of the 2780 (nothing wrong with that one at all).

The 2781 is about 20lbs, a little bulky size wise (base is 6in wide x 13in long) but not too bad. I used to keep it under the rear seat in my 2013 F150 FX4, in it's bag with a few accessories, take it out when needed and toss it back in there when not. Not really a big deal. Now, it stays under the hood of my 2019 ORP, mounted and wired to the dash with a pigtail behind the front, passenger side bumper. I made a manifold, so airing up all 4 at once takes little effort (the manifold is also used for airing down).

I just bought the 150 PSI unit from Harbor Freight and it took my E Rated Grabber ATX 285's from 22 to 40 psi in 90 seconds.
Have only used it twice but for $50 I'd say it's worth a shot.
