I read a few comments regarding the Blue Ox RV underskirt in this forum. From what I understand, the RV underskirt is no longer being manufactured/distributed by blue ox so I would be a little worried about warranty if purchased from a dealer with old stock. I checked the blue ox web site at www.aemfg.com
and the RV underskirt has been removed. I am a Protect-a-Tow owner for a few years and many, many miles and have been very satisfied with how well it works. It is lightweight, compact and easy to use and install.
