Protect your towed vehicle and RV

against dings and rock chips!

 The Guardian is crafted from rotationally-molded, 
high-impact polyethylene to absorb the impact of 
rocks, gravel and road debris — instead of ricocheting 
it back at the motorhome.
  The Guardian can be attached and removed in sec-
onds, and fits all ROADMASTER tow bars equipped 
with quick-disconnects. (Note: MX brackets will not 
accommodate the Guardian.)
  The Guardian can also be used with a tow dolly to 
help protect your towed vehicle by using the Guardian 
bracket (part number 2000-8).
  If you tow more than one vehicle, the second vehicle 
kit has all the mounting hardware necessary to swap 
the Guardian from one vehicle to another.

A bumper-to-bumper blanket of protection!

  The Tow Defender's all-weather, heavy-duty screen 
deflects rocks, gravel and road debris down and away, 
protecting your towed vehicle's finish, headlights and 
windshield against chips and dings. The vinyl-coated 
mesh lets air through, keeping it low and over the 
road.
  Fully extended, both Tow Defenders offer 20 square 
feet of protection, and are held in place with shock-
absorbing gas struts. Once you've reached your des-
tination, roll up the Tow Defender, snap the elastic 
straps around each end, and store it against the mo-
torhome.
• Quick installation and release
• Lightweight and compact — weighs just 14.5 pounds,

and rolls up to four inches in diameter

• Powder-coated steel supports and heavy-duty gas

struts for maximum durability, support and corner-

  ing flexibility

For maximum protection, use a Tow Defender and a Guardian.

  Motorhomes kick up rocks, gravel and road debris, but so does oncoming traffic. A Tow Defender/Guardian com-
bination protects your towed vehicle’s finish, headlights and windshield against damage from both lanes.
