In your first photo it looks like you're about to get poked in the butt by a water bottle if you fall! I GUESS that each Kelty tarp pole is good for a maximum of about 100 pounds of force as long as it is directed exactly along its length-axis. 2 poles are good for 200 pounds.
Half of your 175 pound weight is supported by the Jeep. If we just used 200 pounds for your total weight with the hammock etc, then the 2 Kelty poles only need to support 100 pounds, or 50 pounds each. So, you have a double safety margin, which is what I like to have in any hillbilly-rigging I use.
I like your tow saver strap "hat" for the poles! That's something I wanted to make for a speedy setup and take-down, but lashing them together with paracord has worked well for me. I can quickly set up my hammock everywhere I'm expected to sleep in a bed that's not mine. I never have to deal with bedbugs, funny smells, or "mystery stains"! The best part is I always sleep well because I'm literally sleeping in my own bed, the way I like it to be.
