Roadmaster Tow Defender modification
We really like our 4700 Tow Defender and has protected our toad on numerous trips including our trip to Alaska this summer. Recently, on a return trip from central Texas and after filling up our coach at a local truck stop, one of the 5/16" pivot bolts fatigued and broke. By the time we arrived home, the fabric of the protector and metal square tubing on the driver's motorhome side had ground material and metal off as it was making contact with the road pavement for several miles.
Apparently, this has happened before and Roadmaster has upgraded the two pivot point bolts on the motorhome side to 3/8" specialty bolts and new arms (501301). Contacting Roadmaster, I ordered the two new arms used on the 4800 Tow Defender and will be drilling out the 5/16" tapped hole with a 5/16" drill bit and tapping the collar assembly with a 3/8"x16 to accept the 3/8" bolts that come with the new arms. We look forward to many more trips where this Tow Defender protects our toad.
If you also have this 4700 model, you may want to do this upgrade before you have a broken pivot bolt and have the added expense of purchasing a new protective cover.
