The Aux battery gets a lot of hate, especially from those who don't understand the system, and those that ignore the warning signs of impending failure. The purpose of the Aux battery is to keep the computers stable during ESS events. If you always turn ESS off, having the battery is not...
You can get a comparable price and warranty from Walmart, Sam's Club, and Costco. Everyone else is a little more expensive. The size you want for the Main is 94R (H7). It is the largest the tray will accommodate. Some trucks come with the smaller H6, depending on the options ordered.
I didn't have any issues. Be sure the seller you buy from is Amazon. They don't want a core return. If the batteries go bad during the warranty, they should send either a new battery or a gift card.
Replace them both at the same time. Be careful with the cables so they don't touch anything, I put plastic bottles over the cable ends. Fully charge the batteries before installing them.
With the fuse removed, the startup test is done on the Main battery. Getting the error message shows it...
You're going to get the error until the batteries are charged enough to satisfy the system monitors. The fuse removal just prevents the startup test from seeing the Aux battery, it does not disable ESS or the system monitors.
If you are still on the original batteries, it's time to replace...

With the new...
Have you checked the high current fuses on the end of the fuse box? These can be blown if you are not careful with the cables when changing the batteries.
This may be an option for you. I'm planning to order one. I have a RSI Smartcap to put on, so I don't need a full bedliner.

If you already have the factory inverter and outlet on the back of the console, the wiring should be there to install the bed outlet. @AllMoparParts.com sells a kit for about $300 with the necessary parts.
The best spot is the top of the battery where the other two cables are connected. The second best is the frame ground point where the cable from the top of the battery is connected. This is the one that will be less hassle with the dealer service monkeys.
There is no ESS delete kit. It is part of the system and always active. The button on the dash will prevent it from turning the engine off, when it normally would, but must be pressed at every startup. This is a gift from your friends at the EPA.
