What I see here in general is people cutting long beds down to make short beds. Keep your eyes peeled, some of the experts on here will be able to help.
As for "Custom Camper" and Longhorn, one can get the Custom Camper package even short bed trucks. Longhorn only refers to the added bed length, which of course requires a different frame and wheelbase.
...and "Camper Special" is used by the "blue oval" boys, not the "bow tie" boys.
