TM is known to be more tongue heavy than other trailers, so even though it may be "lightweight" as far as trailers go, there will be more down-weight on the hitch than other similar weight trailers. But, much of the weight will come from how you pack. Because it has holding tanks, a lot of weight can come from prefilling the holding tanks if you are boondocking. Filled propane bottles will add a lot of tongue weight also.
I overloaded the rear axle on our Tahoe which has a pretty decent towing capacity. We had packed a lot of water, and canned food, plus 3 adults and 2 kids. Don't forget the people when it comes to the GVWR for your tow vehicle! 4 adults can add 600 lbs just like that. If they like their beer, closer to 1000 lbs, and that's not just the beer
The beer will be another 100 lbs. (Fortunately, FWIW, I don't drink much beer).
But then, you've done a lot of camping, so you probably know all this stuff already.
