Whatever blows your skirt up...
I use 2" straps, 1 on each corner with a D-Ring axle strap going around the axle tube on each side.
Feel free to pack around all that chain and those binders, I will stick with my straps.
X2, no problem with straps.
I've used both, and still use chains occasionally depending on what it is (crappy, rusted hulk, piece of equipment), but for cars/wheelers, my straps have served me VERY well all these years, with NO failures. I just pay attention to how I use them.
I cross the front, strait back. Just the way I've always done it, mostly cause of my trailers tie-down locations, if they are tight and everything is right, nothing moved.
Chains or straps, stopping a little down the road to check/re-tighten everything is the biggest "good". If its still tight, no foul, if somethings loose, you caught it early.
Good idea to do periodically anyway, especially if you can't see the trailer/load in the mirror well from the driver's seat. Best to take 5-10 minutes to pull off and check things, then to be dragging a strap or chain for the last 20 miles (which makes you look like and idiot, ruins the chain/strap and could be a disaster waiting to happen).
Also, adjust/twist/tie-up the safety chains so they can drag on the ground. I can't believe HOW MANY dragging chains I've seen shooting sparks and weakening them for what you need them. Bungee does wonder's.
