As pointed out above, you need to verify the vehicle’s maximum weight spec’s for the hitch, and probably go to a scale to determine your trailers actual tongue weight. Not safe to exceed that limit.
Then, subtract the actual tongue weight from your vehicle’s payload which is on a sticker on the door jamb. The difference is what you can load into the vehicle, including the weight of passengers. For example, the payload is probably about 1,400 pounds and with a tongue weight of 600 plus 300 pounds of people you will have 500 pounds remaining for all of your stuff. That is not a lot.
Not mentioned previously is the subject of performance, by which I mean the ability to accelerate when needed and to maintain speed on hills and at elevation. This is a personal judgment, but you should be aware the the industry established performance standards are very low — equivalent to a 1962
Depending on your camping style and personal performance standards, this could work or you may prefer something more robust.
