I wrote a long response but the forum timed out and my response wasn't posted
GCVR = weight of rig + tow vehicle.
CCC= GVWR - dry weight
but don't forget the weight of fuel and water, which at 55gal and 42 gal respectively, can add up to about 750lbs.
So the GVWR = 14500 minus full tanks is 13750.
The weights according to Thor (I emailed them) range from 10,800 on the 24.1
11k lbs to 11.5k on the various 25's
and 11900lbs on the 27.7.
So that is a little better than I feared, but it points out the design flaw with the 27.7. It is bigger and looks like it could carry more but since it is built on the same chassis, the 27.7 can carry about 2000lbs of people and gear safely while the 24.1 can carry about 3000lbs of people and gear.
