Go with the 'Rock Tamers' Hands down! I have both. I purchased the 'Roadwing' from Hitchfinder.com and received it from UPS. I then went to the Forums and found a thread regarding rock protection. Everyone likes the Rock Tamer. So, I bought one and I love it, too. Bottom line: Rock Tamer is adjustable. Road wing requires you to cut the mudflap to size! What a @#$%ing joke! You would be really limited by this system if you want to tow with a vehicle other than the one you fit it for initially. Also, I tried to return the Roadwing to Hitchfinder.com and the return request function of their website is disabled and I left messages on 5 different voice mail boxes! To no avail. I think Roadmaster owns Hitchfinder and they were no better at helping me get service from their 'distributor.' If you want to return something to Hitchfiner.com, good luck! I won't, buy from them again. Go to www.Cableas.com
and you can get the 'Rock Tamers' for $199.00.
