As others are saying, payload cap is usually the problem with lighter tow vehicles.
If the above statement is correct, driver and a full tank of fuel are already included. If you have a 1700 lb payload cap on that model try checking it this way to see what you can pull and or carry.
Weight of others in vehicle,
remember kids grow so allow for that 300lbs
weight distributing hitch 100 lbs
Stuff in the truck, coolers etc 100lbs
so 500 or so for the family, leaves you with a little over 1200 lbs for tongue weight.
The maximum towing capacity on those suv's is listed as about 7200 lbs, Tongue weight should be 15% of total weight of the trailer so the tongue when the trailer is loaded for use will be around 1080 lbs.
When looking at trailers look at gvwr, empty weights dont matter, loaded as you will use it is what matters.
By the weights you are probably OK. Also most people will tell you that you should maintain a safety margin of anywhere from 10% of 20% in ensuring that you are safe. If you adhere to that your gross loaded trailer weight should be kept to about 6000 lbs.
If your terrain is flat and level you should be ok with any tt under the above weights. You wont be going fast if you approach those numbers, but with a tow package including brake controller and transmission cooler you should have a manageable rig.
