Pedwards2932, The 4900 lbs. came from the GVWR (rounded up from 4860 - the published number from the spec's - dry weight + payload). The dry weight is an alternate reality that doesn't exist in the real universe. The manufacturers shouldn't even publish it because so many people rely on it to figure out whether they can tow with their current vehicle. By the time you add personal stuff and food and drinks, LP, batteries, some water (fresh, gray, and black), etc., you're going to be very near the GVWR. You may leave with less, but when you go dry camping and fill your waste water tanks and have a little fresh water, it really adds up fast at 8.34 lbs. per gallon. If you travel alone with nothing in your Santa Fe, you'll likely be able to keep the total weight a bit under the 5K, but if you take your spouse, your pet, and the other normal camping stuff in your car, it is almost certain you'll be over weight, a dangerous situation, not to mention that you'll find that your drive train will really show the wear and tear quickly.
It wouldn't hurt, just to be on the safe side, to talk you a Hyundai dealer about your particular vehicle's towing and weight capacity and tell them you plan to tow a trailer that approaches 5000 lbs. I don't think they'd say it's a good idea. And if they do, ask them to put it in writing. Same for your rPod dealer. Ask him/her to put in writing that your Santa Fe can handle the GVWR of the 192. You'll see her/him run out the door to get away, yelling that aliens have landed in the parking lot.
Unfortunately, too many trailer dealers tell people that they can tow with seriously inadequate vehicles because they want to sell trailers and if you have to rebuild your transmission or have an accident, they'll deny ever saying anything about whether your vehicle had the needed towing capacity.
Be careful about calculating your weight capacity in your Santa Fe. You need to look at the CGVWR (Combined Gross Vehicle Weight Rating - the absolute limit for your vehicle and towing load), not the payload. The payload rating is for a vehicle filled with gasoline, passengers, and their stuff. It's not an add on to the towing capacity.
There are a lot of very knowledgeable people on this board who advise not to tow at or near your TV's capacity. Most will tell you to have a 1000 lb. margin of error between your load and your capacity. They speak from experience. No one here want to see this end badly for you or your family.
