Yes that is true, we had the coach weighed with all tanks full, black, fresh, grey, LP, diesel etc. it weighed 23K. I need to tow a Tahoe that weighs between 5,500# - 6,000#. We weighed the Tahoe full of people and stuff and it weighed about 6,600#. No one would be riding in the Tahoe so lower weight. My plan is to carry less fresh water and obviously have empty grey & black tanks. Completely empty the Palazzo weighs about 21,000#. With a 30,000# GCWR that gives you a theoretical tow capacity of 9,000#. That's how Thor gets away with this. Funny thing if Thor had put an Allison MH2500 into the same unit it would have had a GCWR of 33,000# and a GVWR of 28,000#. I checked with Freightliner and they built the whole thing on their standard 28,000# / 33,000# chassis i.e. 10,500# front axle 17,500# rear axle etc. It is the Allison transmission that limits the GVWR / GCWR. Since I plan on flat towing a Tahoe occasionally for short trips that we don't need full tanks because we will be staying at full hookup parks I figured that I would just watch the weights and stay under them.
