manual slider?
i had one it worked great, i was a Husky 16K,
it worked so good at allowing my small bed truck to cruise thru tight parking lots that i started to get a little too brave at how good a driver i was,
... while showing off how good i was at navigating a 5'r thru that crowded parking lot I didn't set the slider back intentionaly, and yea yea yea i crinkled the rear part of the cab a wee bit,
the laughs were on me, and it cost $800 to fix, not bad at all
the moral of the story:
just because the slider works so good, that doesn't mean you've become any better of a driver, it just means the slider works good
