I pull a recently acquired 2007 Chalet Arrowhead Trail Boss version with my 2008 V6 2wd 4runner. This is the 3rd 4R I've owned over 20 years.
Specs on the camper are 1580#, and loaded out I'm sure easy to add another 200-300#. I immediately bought and installed a brake controller to utilize the trailer's brakes.
I'm usually an easy driver, and try to help my vehicles a bit. Coast when possible, use 4th rather than Drive as needed.
Very satisfied with this combo so far. Just did a 400mi trip this past wkd, longest yet. Also have midsize boat, and atv trailer, have pulled these and other trailers for many years with all three 4Rs.
Not much help to you, other than high confidence with Toyota.
That Hybrid might have some wind resistance as well, as approaching high end of weight spectrum?
