Just need a dual head chuck for filling, also on the gauge you carry.
Either,for me, flex hose just easier to twist around. The fillers with gauge are nice as you don't need to remove, then check air with gauge. Though I still use gauge when done. Fillers Im partial to ones with pop out scale verses gauge or window.
You can get a USA made Milton506 for 30ish
or a HarborFreight that I picked up on impulse one day for 7.
You can spend as much or little as you want-several configurations as far as gauges. Other than recommending carrying your own gauge cause Ive found filling station gauges all over the map, is to look at the angle of dual chuck. I have one shown in pic that I use for most stuff around the house, the angle is so shallow physically cannot use inside chuck to fill on the outside dual. Id also not recommend hose extensions on truck. I used on previous MH because of the liners/hubcaps that needed removing, they are more hassle & problematic IMO than learning to seat a dual head chuck.

There are several types of valve extenders.
I used about 1" long extenders when short valve would hide behind inner rim, making it accessible for the chuck. The good ones have smooth cap, that keeps dirt away.
Don't use any hose extenders, as those are often source of leaks and I lost a tire to one of those dually equalizers.
When I like the idea of equalizers, with a gauge with color indication, I would hesitate to use them without TPMS.
I like to air my tires at home not only for the convenience, but also to avoid water some of the service hoses will dump into your tires.
I have oilless compressor at home, what give good air, but is slow with 1 gallon tank.
So my best way is to set the regulator to desire pressure, lock the chuck on the valve and go to other tasks.
After few minutes I move the chuck to other tire and go to other tasks again.
This way I have no surprises down the road.

Good chuck will have ribs inside to hold on the valve when slightly tilted.
This way you can lock the valve and leave it for the time it will take to inflate big tire.
For inflation, read the label on the door to start with.
When front tire pressure is easy to figure out, the rear on dually will change a lot with the load.
When my dually empty should have like 30 psi, the fully loaded comes to 80 psi.
When you drive empty with 80 psi, you better have good dental insurance.
