Features to know about
Made for a Clean Front End: Hidden Design with Removable Arms
This direct-connect base plate gives your setup a clean, factory-style look when you’re not towing. Once the drawbars are removed, the remaining brackets sit back inside the grille and stay practically invisible. That placement keeps everything protected from scrapes and scuffs and eliminates the bulky quick-disconnect crossbar that would otherwise stick out up front.
Quick Hookups Every Time: Twist-Lock Removable Arms
Connecting takes just a few seconds thanks to the twist-lock attachment system. Slide each arm into the bracket, twist to lock, and it clicks securely in place. When you’re ready to disconnect, pull the built-in release ring, twist again, and lift the arm out. It’s a simple, reliable setup that works smoothly whether you’re hitching up for a long trip or stowing things away after the drive.
Solid for the Long Haul: All-Steel, Computer-Cut Construction
Every bracket is computer-cut from all-steel stock for precise fit and exceptional strength. The black powder coat finish adds corrosion resistance for years of use through weather and road grime. Bolting directly to the vehicle’s frame spreads towing forces evenly, giving dependable support over thousands of miles without needing any welding.
Built for Straightforward Setup: Bolt-On Installation with Included Hardware
The kit mounts with standard tools and includes all necessary hardware and instructions for installation—no welding required. Once bolted up, the direct-connect design works exclusively with Roadmaster motor-home-mounted tow bars that slide into a trailer hitch, like the Nighthawk, Sterling, Blackhawk, Blackhawk 2, Falcon, or Falcon 2 series. That one connection point keeps your towing gear streamlined and ready to roll whenever you are.

Once I removed the grill and bumper the install went fairly well. Having an impact wrench is a big plus. Reinstalling the bumper and grill you will have to use the plastic revits they seny with the kit.

We've only towed our Jeep a few times since I've installed it . We did have a tow mishap last year while travelling in Utah after our Bryce Canyon visit. It happened because the cotter pin that holds the left side tow arm pin from disengaging from the Base Plate Removable Arm had sheared off while we were travelling on the freeway. Thank God I installed a rear camera on our Class C RV and I saw it when it happened. I was able to slow down and pull over to the shoulder and once stopped, that was when I discovered that only the right side of the tow arm was attached to the Base Plate. It held up even when the Jeep was fishtailing behind the RV. I was very happy and relieved that there was no major damage to our RV and the Jeep in this mishap.

Until I received the follow up e-mail from Carrieann at etrailer.com, I had completely forgotten about these Roadmaster EZ5 baseplates on my 2007 Jeep Liberty. That sums up my experience and satisfaction. Once installed, I just want it to work and not cause problems that I have to think about or solve.
The RM EZ5 has been easy to use and trouble free. If I were to nit-pick, installation was beyond my capabilities, tools and patience,even with the great eTrailer video. I paid a local shop $200 to install them which included using the proper tool to cut a smooth hole in the bumper cover.
With the arms removed, it's hardly noticeable on the Jeep. Attaching the arms is quick and easy and connecting the tow bar is painless compared to other systems I've used in the past. Yes, they're a tad pricey but they cost less than having the towed go "walk-about" while underway.

Product was perfect fit and seems very solid in it's construction and the way it mounts. I am completely satisfied with the product as i bought both the bracket kit and a wiring kit.
The base plate kit should for this Jeep Liberty 2004 should have included the 6 outer bumper fascia attaching clips because these will break just about every time you take off the front bumper. Also they should supply you with a small tube of Loctite since you will always need it. So for the big price, they should throw this stuff in there but that's just my opinion.
All in all great product, great folks to deal with and I will shop here again

Happy with the finished product, but had real problems installing it. First, the instructions were for a different vehicle than the one I specified. Thank God for the video online: it WAS for my vehicle. A pain running in and out from the computer (I can't see the small phone details), but it worked. Second, the passenger baseplate had what appeared to be a casting mark in a small area where a bolt head was. It was impossible to get a socket or wrench on the bolt; I spent a half hour or so with a file getting rid of a small ridge that prevented the socket from entering the area. The passenger side also did not fit well; all the bolts had to be as loose as possible to get the nuts started, one hole was nearly a half a hole off from where it needed to be. The drivers side was fine in all aspects.
In the end, though, it is on and looks great. Presumably it will tow great as well.

- Parts Needed to Flat Tow 2005-2007 Jeep Liberty Behind RVIn order to flat tow your Jeep Liberty behind an RV/motorhome, you need a base plate kit, a tow bar, safety cables, a lighting solution, a supplemental braking system, and likely a high-low adapter. Starting with the base plate kit, I recommend the Roadmaster EZ5 Base Plate Kit # RM-521423-5.

But the first thing you need to determine is if you will buy one with a brush guard or without. If there isn't a brush guard you'd want the base plate kit part # RM-521423-5 with the Roadmaster Nighthawk part # RM-676. Or if you go with a brush guard you'd want the base plate kit part # 521426-1 with the Sterling tow bar part # RM-576. To protect either tow bar when not in use the cover part # RM-055-3 is recommended...

Since you have a 2007 Liberty you would need to use either the EZ5 base plates # RM-521423-5 or the EZ4 base plates # RM-521423-4. The difference between these is the design of the removable arms.
