We were in a similar situation as well. We had the 38ft 5th wheel then down sized to a 23ft pull behind and now are in a TC. After a couple years in the 5th and tow behind we realized we packed more than we ever used. We actually pulled everything out and realized that we only used about 1/4th of what we ever packed. It was more of the "what if".
I do agree with a couple comments, the sleeping in the cab over, its a change but did not really impact us much. The only issue I have right now as I am new to the TC is the loading and unloading takes me a bit longer than hitching up a 5th wheel and tow behind. Keeping it level...
We do have the eagle cab 1200 and we have used it now just twice but are very happy with the change. We had 4 of us in the this past weekend and it was plenty of room for when we were in side, which wasn't much.
As an additional note, I did drop the extra cash and went the torque lift super hitch 30k and run a 48 inch extension. Well worth it, IMO.
Good Luck,
Brad
