Since my rig is front heavy I store everything heavy behind the tire axle. In my last trip with full water tank, the tongue weight was over 340 lbs. Here are pics of how I load my rig:
The brown bag at the back is the screen room. If the TV could handle the load, the GEN, and jugs of fresh water could go to the front storage. The propane tanks could remain in front.
My front storage is practically empty during transit but I use it for putting extra stuff I don't need in the trailer here after setup.
You got a couple of inches to spare in your garage if you get the front storage.
