Your 4runner should be mor ethan adequate for towing that trailer. Does your 4runner have the tow package? That would be the only thing I can think of. Oh
What about air suspension? If you have that, there's a certain way to hitchup with the equalizers.
Not much else that I can think of.
Have you towed before? If not I'd recommend going on a practise trip just to get the hang of it.
