"It depends". I found my BF 10.5 drove better than the BF 9.6, despite being 600 lbs heavier. In the 9.6, propane tanks, batteries, and holding tank were in the overhang, fresh water tank in the middle. In the 10.5, propane tanks, batteries, holding tank, and fresh water tank are nearly against the front bulkhead, well forward of the axle.
If everything is distributed the same, shortening the camper by 16" will move the CG 8" forward. Moving 150 lbs of batteries from the back to the front can move the CG forward by about 6". If CG is the concern, I would look closely at the details of the individual campers, including manufacturer claimed CG if available.
