Need help from Toyota Highlander owners

It's definitely going to be pushing it to the limit. We pack very lightly and we used up all 550 pounds of cargo capacity in our trailer without carrying any water. Also that tongue weight is under 10% which is not good for towing, but it probably doesn't include battery or full propane tank so it's also probably misleading.

If it were me I'd be look for something closer to 3k listed dry weight as that would give you more margin.
