I like the quadratec stealth bar. Mounts inside the cabin so not exposed to elements/no wind noise/ no drilling. Not exactly the cheapest i guess but works nicely.
I suggest you get a new aftermarket 12V AGM battery first.
For the A pillar mount, a good option is the KC a pillar bracket, it clears the plugin charging port.
Or you can go full ham and get the KC pro 6 gravity light bar with the KC mounting bracket.. that is pretty much your option, unless you go to a Chinese website and find some.
Otherwise you will not find a good one that fits 4xes.
My KC Flex Era 4 just got the delivered yesterday along with their A-pillar mount. Back when I did a thorough research, I narrowed down to KC and Baja. Ended up ordering from KC. I am also planning on getting their 50 inch light bar at some point and FE 3 SAE lights to replace the stock fogs.
