Need to back up to the OPs original question. The "dry weight" or GVW does include the fridge and A/C, as long as they were not additional add-ons. They were taken into account at the factory ratings. Now, if you order your standard TT and request a 2nd A/C be added, you have to add the weight of the 2nd A/C to the "dry weight" to make sure you do not go over the GVWR of the TT. Which means you may have to leave those extra pairs of jeans and your favorite beach chair behind, lol. I agree with others in that you should always have enough TV to pull the RV at maxed out GVWR so that you don't have to concern yourself. Let your limiting factor be the GVWR of the RV, not the combined GVWR of the whole rig.
