John,
Not much to add to the discussion.... do remember that
calculations may not consider the effect of uneven/unlevel
ground when backing into your campsite, or trying to back out
of an oops ! turn. I have the 5ver nose indents on my AF
and the Reese Airborne ... I (slowly)put the TV thru 90
degree turns each direction (on level ground) and had clear
room from contacting the crew cab. Make sure your bed rail
clearance is in that 7 - 8 inch range, as 90 degree turns
really torque the 5ver wheels and can impact side rail clearance
if ground uneven. My 2500HD has the "standard bed".
I have not used the slider... but glad I have it.
