Ah heck, I don't use rod racks (spey fishing) I just brake the rod down into two sections (4 piece rod) and even the 15 footers slid into my VW Jetta. Chicken Little here has had a rod come off the top of the car once ... and only once. Like above the reel took the major pounding but the rod was also gone. And so was about $500.
Three piece Euro blanks are a pain with the VW; here I do have to break them down into the three sections. I don't unstring the rod though. In the Old Explorer; the three piece but mid section are seperated and in she goes.
