lifted truck-using axle straps vs thru the wheels vs chains help

i am hauling a 2016 toyota 4runner, all decked out and expensive. my trailer is a bigtex 14ee-20". the side stake pockets are my anchor points,, big tool box on tongue so not much forward. this thing is proving to be more difficult to secure than i would have thought. it has a fancy aftermarket suspension on it so i don't want to squish down the suspension by hooking to the above suspension area. i was going to use axle straps on rear axle but just a ton of #### in the way that i don't want to break,, like the brake lines ,,,,, and it doesn't even have a front axle. so it looks like i need to run my axle straps through the wheels,, my trailer attachement points are mostly on the side of the trailer in assorted spots, so the pulling load will be sort of mildly pulling the front tires into a "toe-out" manner. same on rear tires but not as worried about those.
