Towing Capacity

Thanks for all the responses! This is what I expected but glad to hear from people with experience. I figured this set up was pushing the limits. But being new I do have some more concerns that maybe someone can clear up for me. You all mention to ignore dry weight of the TT and use the TT GVWR for calculations. The TT and TV setup I questioned above DRY WT was 5800 and GVWR was 7500. Even though I used an estimate of 6500# loaded was still pushing the limit, and obviously 7500# I am def. over weight on TV GVWR. My back up TT I was looking at has a DRY WT of 4700 but a GVWR of 7400. Now if I am to ignore the dry weight and use the GVWR I am in the same situation as before. But there is no way I will be loading 2700# in that TT! This is why I don't understand ignore dry weight comment. I figure with the TT loaded I am looking at 5400-5600# loaded. I just don't see how you can ignore dry wt. completely. Most TT I've looked at vary in payload capacity's from 800's to 2,500's! But my realistic cargo wt. will be in the 600-800 range max. Am I wrong to consider dry wt. as a starting point for an estimate of actual weight??
