Want the real story (and the only truth) ask someone to tow your rig across the scales after you pack it up. Then work from there on what you really need and want for a safety margin knowing exactly what you have.
Everyone will have opinions and they may or may not be good - the scales don't provide any opinions, just facts.
We have a 2011 RAM3500 DRW/CC/LB/CTD because we have a heavy rig (similar weights to you) and don't want to have issues with wind, hills/mountains, etc - Sure I have seen our rig towed with a SRW but the weights that we have just don't support using that and still having some capacity in the bed of the truck for stuff.
My only opinion is to be safe in what ever your choice is and recommend you use the scales to determine the correct TV.
