Hi Sandyc,
We have been towing a 2006 Jeep Liberty 4WD for 7 years now with a Roadmaster Falcon-II tow bar and Unified Tow Brake and are happy with the setup and ease of use. Our Liberty weighs 4300 pounds. We got so good at unhooking and re-hooking that when working together, my wife and I can unhook and send her off in the Liberty in 45 seconds. It takes 3 minutes to hook back up. We work together like a pit crew when we have to.
Having the manual shift transfer case with the 4 settings of 2WD, 4WD, Neutral, and 4WD-LOW, makes for a perfect tow. The main transmission gear shift lever stays in park so the transmission itself does not rotate while being towed. The transfer case goes into neutral so all the spinning action is safely done inside there. No fussing with running the tow vehicle through gears every few hundred miles as is common with other automatic transmission tow vehicles.
The Unified Tow Brake system is very effective, so much that I upgraded the Liberty's 4 rotors to performance drilled & slotted, and pads to performance ceramics. They further increase braking performance, so much that the Liberty slows down the motor home much better than when driving the motor home without the Liberty in-tow.
The Liberty tracks perfectly behind the PC. Once up to speed, we don't feel it back there. Watching it on the back-up monitor, it is very well behaved.
The only issue we have with our Liberty is a problem that may be common with many different tow vehicles. The inside edges of the front tires get worn quickly from doing sharp right-then-left, and left-then-right turns with our PC in parking lots & gas stations and such. The Liberty steering wheel doesn't seem to turn sharp enough when the vehicle is being pulled like that. Regular turns and such are perfectly fine. It's only a problem when doing that quick right/left thing with our PC. Our Liberty wheels and tires are both stock. If we had huge aftermarket tires and wheels with offsets, the condition would be much worse. Whatever vehicle you tow, I advise to keep the wheels & tires to the original specifications to keep the strange front tire wear under some control.
If considering a Wrangler, heed this. I knew someone who went through two rear PC windows because the Wrangler front fendors do not cover the wheels adequately. Stones get thrown forward at the PC breaking the rear window. I do recall his tires were very aggresive, able to capture then release large stones. You may want to invest in a towing shield.
