Lippert owns TrailAir. Can't see any warranty problems if you use their own product. I have a TrailAir with the Tri-Glide jaw. I'm thinking they might just discontinue the Tri-Glide soon now that the FlexAir version is out. Tri-Glide has 9 grease fittings you need to hit every thousand miles or so. FlexAir won't require that. My Tri-Glide bumps and bangs on starting and stopping at times. The brake control needs to be just right. There have been some issues with the Tr-Glide jaw coming apart. They develop a lot of sideways play in a few of them. I wouldn't buy another. JMHO
