As your aware, staying within your TV's weight limits, a properly sized/adjusted
WDH, and a lot of common sense keeps most of us out of trouble.
As mentioned earlier, taking your SUV to a CAT scale under loaded camping conditions and weighing it is a good start...., then subtracting your CAT scale weight from your TV's GVWR will tell you how much "available" payload capacity you have for a TT's loaded tongue weight (and a 50lb WDH). Knowing this information prior to an RV dealer visit would be very helpful with your do diligence.
As you stated the 27DSRL is a 31ft long TT, and having adequate tongue weight on the TV's hitch ball will enhance a TV's the handling of a heavy/long TT. IMO you would want nothing less then a 13% loaded tongue weight, but 15% would be my ideal comfort zone.
I agree with "Camper_bob" in using a "15%" loaded tongue weight with your estimated 27DSRL loaded weight.
Also, towing with an "LT" tire on your SUV will enhance it's handling characteristics with the heavier/longer TT.
