I've had this same thought several times, and have really given this a lot of consideration. I've confident in my decision that the Power Wagon is the right choice for my build. I'm not expecting to replace the radius arms, but its an option if needed. I have a full shop, and the knowledge and skills to align a live axle vehicle myself, Swapping arms would just be part of prep before going on vacation. Realistically, Hope will be spending 95% of her time empty one the streets and exploring the back country. I'm going to make a few mods to increase her capacity, without reducing her capability.
I'm pretty knowledgeable about 3, 4, and 5 link suspensions, but honestly, I've never used a radius arm setup before, it was always easier to build a 3 link front. So I'm still learning about them. If I post something incorrect about a radius arm, let me know. Here's a pic of the 4 link rear I'm finishing up on my TJ.

The sway bar disconnect is actually a big deal. When disconnected the front axle can move independently of the body allowing for greater flex and articulation, which is great for off road, but what they don't tell you is how much it improves the ride. It goes from violently tossing the vehicle around side to side to being very smooth. The difference is night and day. On the very rocky terrain I frequent, I cringe watching the HD trucks lumber along at 3 mph. Every bump and small rock throwing the truck and its passengers around. I'm always surprised the YouTube guys never mention it.
These is another side of this coin. I own a jeep rental business in Sedona. This truck is replacing my gladiator which is the primary recovery vehicle for whenever a mechanical problem happens or someone gets stuck. The truck has to be just as capable as a Rubicon, so it can get them out of trouble if needed. So lockers... an absolute must. Winch... an absolute must. Sway bar... an absolute must. I think of the Power Wagon as a Gladiator on steroids. Nearly as capable off road, but with the ability to tow and haul. Here's the Gladiator I'm replacing.
