VIAir connection thoughts
I'm going to be getting the VIAir compressor for the 5'er. You're supposed to connect it directly to the TV battery. My unit is pre-wired with the Furrion solar charger port. I'm considering using the port as the battery connection as it is wired directly to the RV battery, and easily accessible. I think this adapter plug will do the trick.
Has anyone done this?

LMAO. I just said to my wife yesterday that I was thinking of wiring up a SAE connector to power it so I didn't have to deal with the battery connection every time I used it. I was going to go this route for the connector as you can then have one that still has the battery clips that you can use it away from the rv buy I do like the fact that the one you posted has a "wall mount". My idea is to put it in one of the cabinets next to the battery box.

I don't see any reason why your idea wouldn't work. If the goal is to plug in from afar, you just need to ensure that you have the proper gauge wiring to carry 30A DC for that distance.
If you haven't committed to the purchase yet, I would highly recommend considering on board air. I've gone the 450P-RV route before, and now I have that compressor permanently mounted in my toolbox with a quick connect on the outside. I'd much rather just lug a hose out than a compressor each time I need to use it. I also had a real OBA system on my old truck, with tank and all, but sold it with the vehicle.

it would work. i believe they want the compressor connected to a battery on a running engine so that the battery is getting a charge. the concern would be that running the compressor off a static battery for an extended period of time would discharge the battery. i've seen posts where people say it takes some time to fully inflate larger rv tires.

That makes sense. My tires require 110 psi, but I would just be topping off typically.

Those last few PSI are at the highest pressures and thus take the longest. To go from 100 to 110PSI, you're probably talking about 4min per tire.
Rough math: assuming an 85AH Group 27 lead-acid battery, you should have about 1.7h of run-time, about half of that all you want to use. It should take about 16min to fill four tires - so you should be okay as long as the battery is healthy to begin with. You wouldn't want to run the compressor more than around 50min without charging the battery.
