Expert Answers about Jeep JL Wrangler Unlimited

• Recommended E-Bike Rack for 2018 Jeep JL with 35" Spare Tire
• In order to find a suitable bike rack for a vehicle with rear spare tire you'll need to measure from the center of the hitch pin hole to the outside edge of the rear spare tire. This can then be used to determine compatibility as we list the distance from the center of the hitch pin hole to the closest part of the rack on most of our bike racks. The Swagman Current Bike Rack part # S64678 is a good option and measures 12-3/4" from the center of the hitch pin hole to the closest part of...

• Does The ThermaHeat RV Holding Tank Heater Pad Require Special Wiring
• You'd most likely be fine just using some # 16-1-1 with the standard casing but you could also get some wire with exterior rated jacketing if you wanted to go the extra step. You can also get some wire loom # 7509-10 and run it the length of the wires and use electrical tape to secure it. When installing the ThermaHeat RV Holding Tank or Step Heater Pad w/ Thermostat # 277-000164 you'll also want to use a switch like # 37212595 to be able to turn it off when not needed to avoid an unwanted...

• Cargo Carrier Options for Jeep Wrangler Unlimited to Keep Rear of Vehicle Accessible
• I understand your cargo carrying requirements and I can relate to the dog-friendliness requirement too. I have a suggestion that will let you approach this need from a literally different angle: a front-mount hitch. Draw-Tite front-mount hitch # 65079 will fit your 2018 Jeep JL Wrangler Unlimited if it has the standard factory front bumper. This 2-inch hitch installs without drilling using included hardware and just a bit of fascia trimming will be needed. The advantages of a front hitch...

• Can Redarc Smart Start Battery Isolator # 331-SBI212D pass 200 Amps to Deep Cycle Battery
• The Redarc Smart Start Battery Isolator # 331-SBI212D that you referenced would work well for you since you need to pull 200 amps through it from your starter battery. I attached a diagram that shows how this wires to your setup as well. This has a max continous current of 200 amps and can be used with LiFePO4 batteries.

• Best Trailer Hitch for a 2018 Jeep Wrangler JL Unlimited
• The best trailer hitch for your 2018 Jeep Wrangler JL Unlimited is the Draw-Tite Max-Frame Trailer Hitch Receiver # DT78MR because it has a higher weight rating than the other trailer hitches available (indicating a stronger construction), has a longer receiver to help accessories clear your spare tire, and features safety chain loops that remain under your rear bumper for a clean look after the installation. I have attached pictures and an installation video for you to reference. For...

• Can 3rd Brake Light on 2018 Jeep Wrangler be Used When Flat Towing
• The 3rd brake light on your 2018 Jeep JL Wrangler runs on a separate circuit so while it's possible to have it activated while flat towing the vehicle it's not something that any of the harnesses we have available are designed to work with, including the Roadmaster Diode Kit # RM-15267 that you referenced. If you really want to activate the 3rd brake light you will need to add a converter like # 118158 that will tap into the combined turn/brake circuits on the Roadmaster harness. On the...

• Tow Bar Lighting and Charge Line Kit for 2018 Jeep Wrangler JL Unlimited
• For tow bar lighting/wiring for your 2018 Jeep Wrangler JL Unlimited we have the Roadmaster part # RM-15267 which would work great. It splices into the taillight wiring so that your motorhome can easily control the lights of it. I attached an install video for this for you to check out as well. Then to charge the battery of the Jeep while it's being towed you'd want the part # RM-156-25 and you'd be set.

• Best Front Mount Hitch for a 2018 Jeep JL Wrangler Unlimited
• The best front mounted trailer hitch we have for your 2018 Jeep JL Wrangler Unlimited with the standard front bumper is the Draw-Tite Front Mount Trailer Hitch Receiver part # 65079. This hitch is a custom fit for your Jeep and installs using pre drilled holes in the frame. In order to install this hitch you will need to trim the plastic air dam and remove the metal one but there will be no way around this for a front mounted trailer hitch. I have attached the installation instructions...

• Yakima FullSwing 4 Bike Rack Compatibility with 2018 Jeep Wrangler Unlimited Sahara
• The Yakima SwingDaddy 4 Bike Rack has a distance from center of hitch pin hole to top of upright bar of 9 inches. If you don't already have this hitch, then you may want to consider the Yakima FullSwing 4 Bike Rack # Y02465 which has that same 9 inches from the hitch pin. Depending on the hitch length and the tire width, you may or may not need a hitch extender like the Curt # C45791. Using a hitch extender will reduce the hitch's tongue weight capacity by 50% which shouldn't be an issue...

• Recommended Tow Bar Lighting with 6-Way Connector for 2018 Jeep Sahara Unlimited
• To wire your 2018 Jeep Sahara Unlimited like you described in your question so that it accepts the RVs tail, brake, and turn signal lights, I recommend the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267. This kit includes everything needed to wire the Jeep and also connect it to the 7-Way on the RV. It includes the 4-wire harness for connecting to the Jeep's tail light circuits, 4 Hy-Power diodes to prevent feedback from the RV, a 6-Way connector that will mount to...

• Will Roadmaster InvisiBrake Work When Towed Vehicle Engine is Off and Power Brakes are Not Active
• I took a look at the online owner's manual for your 2018 Jeep JL Wrangler Unlimited and it does say to turn your engine off before flat towing. This does make pressing down on the brake pedal much more difficult but supplemental braking systems like the Roadmaster InvisiBrake # RM-8700 are built to accommodate this. If you have tried flat towing your JL and you are experiencing problems then please let me know. However if you just sat in your Jeep with the engine off and tried applying...

• Troubleshooting Tail Light Flashing with Flexo-Coil Kit Installed on 2018 Jeep JL Wrangler Unlimited
• Start off by checking the 6-Way connector at the front of your 2018 Jeep JL Wrangler Unlimited. Be sure that none of the wires are touching any wires next to it which would allow power to jump from one circuit to the other. If that looks good then the next step is to troubleshoot the diodes that come with the Flexo-Coil Wiring Kit # RM-15267. Since the problem is only happening to one side simply remove the diode on the circuit that is messing up and swap it with one on the other side...

• Is Demco Tabless Base Plate Kit # DM9519336 Compatible with Blue Ox Tow Bar
• The Demco Tabless Base Plate Kit # DM9519336 that you referenced will work perfectly with your Blue Ox Avail Tow Bar as long as you add the Demco Adapter # DM9523127. The adapter is what will allow the tabless base plates to attach to the Avail Tow Bar. I absolutely agree that the Demco Base Plate Kit offers an extremely clean appearance as there won't be any protruding brackets. I have attached an image of this kit installed on your 2018 Jeep JL Wrangler Unlimited that you can check...

• Ski/Snowboard Rack for 2018 Jeep Wrangler JL Soft Top
• The only bike rack solution we offer for your 2018 Jeep Wrangler JL Unlimited will be a hitch rack that can use the Yakima Hitchski part # Y02418. Yakima states that only Yakima bike racks can be used with the Hitchski like the Ridgeback part # Y02458. You'll need a hitch installed on your Jeep which the best option is the Draw Tite part # DT78MR since it sticks out the furthest from the bumper to help fit past the rear bumper.

• Parts Needed to Flat Tow a 2018 Jeep Wrangler Unlimited JL w/ a Roadmaster Falcon 5250 Tow Bar
• We have what you need to have a cleaner appearance on your 2018 Jeep Wrangler Unlimited JL. You will want to use the Roadmaster Direct-Connect Base Plate Kit # RM-521453-5 which uses a direct connect attachment style which eliminates the crossbar that you did not like to see. I contacted the manufacturer and they verified that the Roadmaster Falcon 5250 can be used with the direct connect base plate kit. I have attached a video that goes over an installation of the base plate kit and shows...

• Tow Bar that Can be Used with Roadmaster D-Ring Adapter RM-035
• The Roadmaster D-Ring Adapter part # RM-035 that you referenced is the correct adapter to use with your bumper but the etrailer tow bar part # e74zr cannot be used with it as its inner arms (where the adapter attaches to it), are different from a Roadmaster tow bar like what this is designed for. Instead you'd need a Roadmaster tow bar like the Falcon part # RM-520.

• Timbren Axeless Suspension System For 5 on 5 Bolt Pattern Wheels To Help With Tire Clearance
• I can certainly recommend a Timbren axle-less system for you. The Timbren Silent Ride Suspension does not have a bracket to flip the axle because there wouldn't be a way to attach the system to the frame if the axle is flipped. When you "flip the axle" you are putting the leaf springs or suspension above the axle which is not going to work with the Timbren Silent Ride system. I also checked to see if they had any spacers available to help with tire clearance and they do not. I recommend...
