  • Parts Needed to Flat Tow a 2005 Jeep Wrangler with a 2014 Silverado 1500
    If you already have Roadmaster base plates installed on your 2005 Jeep Wrangler then the RoadMaster Base Plate to Blue Ox and Demco Tow Bars Adapter # RM-033 and the Blue Ox Alpha Tow Bar # BX7380 are a great selection. If you don't already have a base plate kit installed then you will need to choose one from the linked selection as they are bumper specific. If you are unsure what you have just send me a photo and I can identify what you have. Since the Blue Ox Alpha comes with safety...

  • Parts Needed to Flat Tow 2002 Jeep Wrangler TJ
    Hey Sam, I attached a link down below that will let you see all of the installers in our area that you can pick from. For parts I would go with the Roadmaster base plate kit part # RM-521424-5 as it's easier to use and installs relatively easy. In addition to the base plates, you will also need a compatible tow bar, safety cables, lighting, and supplemental braking to flat tow your vehicle. The most popular compatible tow bar is the Falcon All Terrain, # RM-522. This has non-binding arms...

    First thing you need to flat tow your 2003 Jeep Wrangler is the correct base plate kit. For that you would want the Roadmaster EZ4 kit part # RM-521424-4. In addition to the base plates, you will also need a compatible tow bar, safety cables, lighting, and supplemental braking to flat tow your vehicle. The most popular compatible tow bar is the Falcon 2, # RM-520. For safety cables you can use # RM-643. The coiled design helps keep the cables off of the ground. For lighting you can use...

  • What Do I Need To Flat Tow A 2004 Jeep Wrangler Behind A Motor Home
    I am happy to help you find the parts to flat tow your 2004 Jeep Wrangler. The Roadmaster Direct-Connect Base Plate Kit part # RM-521424-5 is a better option for a base plate compared to the Roadmaster # RM-521424-4 that you referenced because the Roadmaster Direct-Connect Base Plate Kit doesn't require you to leave the crossbar of your tow bar on the base plate to use the quick disconnect like the slightly older version. The Direct-Connect is a bit easier to use. I attached a video that...

  • Can a Jeep Wrangler be Flat Towed by the Front Bumper
    I have a solution for you, however, I would not recommend mounting a tow bar directly to a bumper on a Jeep, whether it is OEM or an aftermarket bumper. Jeep does not recommend towing the Wrangler with the OEM bumper because it was not designed to pull the weight of the vehicle. Also, mounting a tow bar to a bumper would require drilling. I spoke with my contact at Pavement Ends and she said drilling into this bumper would void the warranty and they do not recommend using it to tow the...

  • What Is Difference In Roadmaster XL Base Plate Kit, # 1420-1, And # 1424-1, For 2002 Jeep Wrangler
    For your 2002 Jeep Wrangler the difference in the base plates is different application for what type of bumper you will have on your vehicle. The Roadmaster XL Base Plate Kit, # 1420-1, will fit a 1999 to 2002 Jeep Wrangler single tube bumper or a U-channel bumper. The Roadmaster XL Base Plate Kit, # RM-521424-4, will fit a 1997 to 2006 Jeep Wrangler double tube bumper and fits the Unlimited and the Rubicon. It will not work on Jeeps with front leaf springs. The visible portions of...

  • Parts Needed to Flat Tow 2003 Jeep Wrangler behind Motorhome
    To flat tow your 2003 Jeep Wrangler will require you to install a base plate kit so that you can use a tow bar. Trying to flat tow from the bumper isn't a great way to accomplish flat towing as most bumpers aren't rated for flat towing. Since most likely you have a stock bumper (u-channel or double tube) you'd want the base plate kit part # RM-521424-4 which is confirmed as a fit. In addition to the base plates, you will also need a compatible tow bar, safety cables, lighting, and supplemental...

  • Blue Ox Base Plate Kit that Fits 2005 Jeep Wrangler
    Blue Ox makes a base plate kit that fits your 2005 Jeep Wrangler with a standard bumper with the part # BX1120 which will work great with your Blue Ox tow bar. For lighting you can use the diode kit, # RM-15267, and not have to worry about cutting into the taillight housing. This will splice into your taillight wiring to allow your tow vehicle to control the taillight assemblies of the towed vehicle. This comes with a round 6-way connector that you will install on the front of your towed...

  • How To Use a Tow Bar On a 2005 Jeep Wrangler with Metal Bumper and No Base Plates
    The Replacement Quick Disconnect Crossbar Assembly part # 910021-00 is designed for use with Roadmaster Crossbar-Style Base Plate Kits like part # RM-521424-4 which is a fit for your 2005 Jeep Wrangler so I cannot recommend that you attach this directly to what I presume is a metal bumper. If you have a motorhome mounted tow bar like the Roadmaster Falcon 2 Tow Bar part # RM-525 then the best option for you would be to weld a set of d-rings onto your front bumper which would then allow...

  • Baseplate or Adapter Compatibility with Warn Bumper on 2013 Jeep Wrangler Rubicon
    If you don't have the Warn Elite then you would need to confirm with the manufacturer that the bumper is rated for flat towing versus just trusting forums. If it is rated by the manufacturer for flat towing then you can use the Adapter for Jeep D-Ring Bumper Mounts to Roadmaster Motor Home Mount Tow Bars - 1" Thick # RM-035-1 or # RM-035 for the 3/4 inch thick. If your Warn bumper is the Warn Elite, then you can use the Roadmaster Direct-Connect Base Plate Kit - Removable Arms # 1439-3.

    Unfortunately, there is not an adapter available that will allow you to use the Stowmaster 5000 tow bar with a set of Blue Ox base plates. This means that you also would not be able to use the Roadmaster Guardian 2nd Vehicle Kit, # RM-4000-1, that you referenced. You have two options. First, if you want stay with your Stowmaster tow bar you could go with a set of Roadmaster base plates on your 1997 Jeep Wrangler.

    I would be happy to explain the flat towing procedure for your 2005 Jeep Wrangler. This information can also be found in the owners manual under the Recreational Towing section.

  • Preparation Procedure for Flat Towing 2009 Jeep Wrangler with Manual Transmission
    When the transfer case of your 2009 Jeep Wrangler with manual transmission is placed into the Neutral the driveshaft will be disengaged from the powertrain. This will allow the vehicle to move with all wheels down despite the transmission position. The owner's manual does not specify which gear to use, as you noted, but most owner's put the Jeep's manual transmission into 2nd or 3rd gear based on what I read online. You might contact a local Jeep dealer with your Wrangler's VIN which...

    When flat-towing a vehicle like your 2002 Jeep Wrangler behind your motorhome, there are 5 items needed. You will need base plates, a tow bar, safety cables, wiring for the towed vehicle and most states now require a supplemental brake system. Just in case you do not have all of these items I will make some recommendations that will work for you.

  • Can I Dolly Tow a 2000 Jeep TJ Wrangler
    From what I was able to find in the owner's manual of the 2000 Jeep TJ Wrangler, you're not supposed to tow the vehicle on a tow dolly that leaves only 2 wheels on the ground (I do believe it's because of the transfer case). You can either flat tow the vehicle or tow it on a trailer/dolly that keeps all 4 wheels off the ground. In order to flat tow your TJ you'll need base plates, a tow bar, tow bar wiring, safety cables, supplemental braking and in most cases, a high/low adapter. I've...
