Problem is the same length camper will make your rig longer on a SB truck than a long bed truck. The camper is roomier because it is a bigger camper. However, a 9-2 camper designed for a short bed truck will stick out the rear almost 3'. This will mean you will need a hitch extension like super truss if you plan on towing anything.
A 9-2 camper designed for a long bed will only stick out the back about 14". It will also allow you to tow most things with a simple 12" or 18" extension.
There is a reason that the camper is still on the lot. 9-2 on a sb is a long camper.
