The 2500HD engine and tranny is "strong" but the truck only has a GVWR of 9200 lbs.
To stay within the GVWR - You will want a truck with a GVWR of 11,500 or better. Newer 3500HD (2011 or newer) or a 2010 or older dually.
So go for the Ford - it should have a GVWR of about 11,500 if it is SRW - more if it is a dually.
I have a friend that has been looking at used trucks and the Fords are going for $4-5,000 more.
The Ford new was probably "stickered" for $55,000 or more.
My CAT scale weight (loaded for 2 weeks of camping; gray and black tanks empty and 1/2 tank of water):
Steer Axle - 4900 lbs
Drive Axle - 6060 lbs
Trailer Axle - 9220 lbs
Gross Weight - 20,180 lbs
I am sure your trailer weight and pin weight is more than mine. This should be info on your rig - your weight from the factory is more that what is advertised (options).
