Larry,
Thanks for the comprehensive response! I was indeed referring to 90 degrees between the truck and the trailer for backing up. I don't think I'll ever need it, and I know it's hard on the trailer/tires, but I was just curious more than anything.
Most of the guys on Duramax Forum say a slider is either unnecessary or they've never used the one they have. I really like the idea of the B&W Companion</span>, but it's not a slider... I just wanted to try and get some feedback from other Cruiser owners that I'll be OK without the slider. Honestly, I'd be very surprised if I can do the 90 degree "jack knife" without the slider - but I'd probably never need to.
The reason why I'm being overly cautious is I'm currently a single guy, so there may be times when I'm jockeying the trailer on my own. That was part of the reason why I went with a fifth wheel versus a standard TT... Tows better, shorter overall length, more maneuverable</span>, easier to hitch up, etc. My second set of eyes when other friends aren't around will be a Swift Hitch wireless camera positioned strategically outside the rig.
I just don't want to be the next YouTube video of a guy taking out his back cab window with his 5er
