Hi Sharon,
Just like you say, there are many opinions and experiences. I will share my experience only for reference. I can say the method we had chosen back in 2007, continues to serve us well today.
Back in 2007 when we bought our PC, we had a 2000 Toyota MR2 Spyder that we wanted to tow. I went with Roadmaster's Falcon-II tow bar because they offered the tow bar bracket kit for that specific car. Because the tow bar was level with that little car, I did not need a riser or reducer. The car was barely legally light enough that I did not require a tow brake so we did not have one. Here is the very simple setup we had back then.


After 2 years towing that, we bought a 2006 Jeep Liberty 4x4 to enhance our adventurous capabilities. I bought the Roadmaster hardware kit for that and continued to use the same Falcon-II towbar which we use to this day.
I first tried to tow our Liberty with the bar not level as shown which was a really bad idea because it caused lots of horrible "bucking".

I then added a riser to level the tow bar which eliminated 100% of the bucking. Adding the riser increased the distance between vehicles so I had to also buy longer blue safety cables. I use 2
QUIET HITCHES at the 2 connections which eliminates various towing clanking sounds along with minor play.


For our Liberty, I bought a Unified By US Gear tow brake that works well. I believe the system is no longer available for sale today. Here is the system diagram. It is fairly complicated, but once installed, is very effective and easy to connect and disable on trips and when back at home. This braking system continues to work well for us for all these years. What I really like about this particular tow brake is that the Liberty's brakes contribute so much that the braking distance of the over-all train is noticable shorter. We brake better and faster when towing than when not towing. I don't worry about prematurely wearing out our Liberty's brakes as brake jobs on that vehicle are very simple and affordable, especially doing the work myself.

On trips, I always leave the tow bar attached to the back of our PC, so I only mess with all that heavy lifting only at home.
For the record, I installed and wired everything I covered here for both vehicles myself.
I also want to share that regardless of the towing system you decide, towing 4-wheels-down, you cannot backup...not even if you have someone in the tow vehicle steering it. It does not work, period! Every extended trip we take, it seems there is always one time during the trip that I get us into a bind where we have to separate the two vehicles in a hurry. I have timed the process. With Irene doing her part in her Liberty (yes it is "her beloved" Jeep), we are both able to drive off in under 45 seconds. Rehooking up at a safe location, it takes under 4 minutes.
Again, I share this for educational reference. I don't think it is the best, nor less than the best. It is the only setup I have experience with.
Now, concerning your Jeep Wrangler..........
Many years ago now, a couple who owned a PC, stopped at our house to buy something from me during a trip they were on. We also shared ideas and such. They owned model 2350 built on a Sprinter chassis, towing a same year Jeep Wrangler. I saw that their rear window was shattered. They told me this was the second time they lost their rear window. They told me that the aggresive tires on their Wrangler was throwing rocks forward through the front opening in the front fender. They were thinking the rocks were deflecting off the top of the Wrangler's front bumper, then shooting up towards the PC's window.
I see in more recent years, some Wrangler models have an added filler piece as shown. I don't know anything about them, but it seems a good idea to have them.
