I read somewhere that how much 'people weight' and 'cargo weight' you would you carry in your TV, affects your actual safe maximum trailer towing weight capacity (in a convoluted way I still do not understand). There is a rating we'd ALL love to know for our TV, GCWR (Gross Combined Weight Rating is the mythical maximum total loaded TV weight + Loaded Trailer wt.). Unfortunately, most auto manufacturers do NOT publish this spec. and for my 2017 KIA Sorento, a zillion web searches, emailing my Kia salesman and that dealers service dept.... Crickets. HAH, the manual says: "Warning. Before towing, make sure the total trailer weight, GCW, GVW, GAW and trailer tongue load are all within the limits." Nowhere does the manual give a number for GCW or GCWR! Maybe someone has heard of a rule of thumb to arrive at a ballpark GCWR for TV's. I want to use that data point not to max out my (supposed/ implied 5000 lb tow cap, but to learn if it is really WAY less once you account for the actual weight of the TV and all people, cargo & tongue wt. and balance with the TV's GVWR limits . Using my vehicle, cargo, tongue wt. max as an example, what would you say the maximum trailer weight would be here specifically? (not including tongue wt, which is included in TV 'cargo') 2017 Kia Sorento SX AWD, 3.3L V6, 5000 tow cap, 350 max tongue wt. GVWR 5622 Curb Wt. 4101 Cargo cap 1521 (5622-4101) Cargo Wt. 600 (2 people, pets, generator, coolers, Tools/Chrgr, Wood, Clothes/misc) Cargo Cap 1521 - 600 cargo - 350 Tongue = 571 lbs of capacity left over in TV I guess. The goal of this exercise is NOT to learn the maximum trailer weight, so I would choose to tow that amount. I want to know this number so I know with 'X' weighted trailer, I am towing 'Y%' of my capacity. Where 'Y' might be somewhere between 65% to 80% of capacity. It is helpful when shopping for 'how much more Pup size' do we feel comfortable towing. Then factor that into our size/model selecting process. Thanks for any insights or additional considerations.
