If the MY RST chassis is capable of towing up to 11,600 with a swap to the gas 5.3L from my 3.0 duramax, does it make much of a difference if I max out the tongue weight or go a bit over it with a trailer? Keep in mind the trailer would still be below the 3.0's reduced tow max of 9300lb, which I've read is reduced due to heat with towing inside the engine compartment with the new 3.0 duramax.
I ask this because I'm looking at buying a sub 6000lb UVW toy hauler, but some of the tongue weights are floating between 750-1120lbs. One that I like is 920lb, but I'm sure I might go over that with anything added to bedroom area......but I suppose the 800lb in bikes in the back would reduce some of the nose weight. I've done estimations on a couple of trailers adding bikes, gear, people, food and liquids and would be under the max towing weight. My only concern it tongue weight, but the RST hitch should be able to carry more weight than the 10% listed by GM.
