Dry weight + battery/ies + propane tank/s + spare tire + water (30gal) + mandatory equipment (power cord, water hoses, sewer pipes, chocks, leveling boards, etc) would give you around 150 pounds of personal equipment (food, clothing, linens, dishes/cooking ware, etc)
to stay under 4000lbs towing.
Overall.. you would be around 1000lbs under your max gross weight (TV and TT combined), 2000lbs under max tow weight, and payload capacity maxed out. Anything over +/- 150lbs in the trailer will put you over max payload capacity of your TV and be cutting into your 1000lb max gross weight cushion.
"CAN" you tow it? More than likely yes. "SHOULD" you tow it? That's for you to decide. As you can tell.. I am a stout supporter of towing within your rigs capacity with a margin of safety to spare. You may be under in some areas, but over capacity in others.
Many folks run WAY over ratings on a regular basis because they can.. until they can't. I do know that it is a fact that the #1 cause of accidents involving RV's is overloading.
One other factor to consider is if you DO get in an accident while towing, one of the first things your insurance company will do it weigh out your rigs. If you are overweight they don't pay. [edited: "may" not pay ;-)]
I'll get off the soap box
Each must decide for themselves what risks they are comfortable with.
