Thanks for all the helpful input.
I had a slight feeling the jayco x18d might have been pushing it, especially tring to keep to the 80% rule. The other trailer in mind is the jayco x17z model. The estimated dry weight on that unit is 2785, tounge weight of 395 and GVWR of 3500. Would this be a better match? Or will I be limited to a pop up trailer due to the hitch design being bolted to the crossmemeber vs the frame. As someone stated previously, no one makes a frame mounted hitch for the 5th gen 4runner yet, so I'm left with the stock hitch from the factory.
If I were to pursue a smaller hybrid, will a sway only control hitch be sufficient without the WD?
crcr, where does the scan gauge pull the trans temp from? Do i need to add some type of temp sender inline on the tranny?
