The set up looks clean.
I too was concerned about paint damage during the hauling tie down process.
I was also concerned about strain on the tractor and the trailer (tandum axle 7,000 cap) so I use tie down straps.
I bought them at Home Depot each is rated for 500+ and I use six on the tractor and one on the 3-pt equipment if any.
The tractor gets tied down with four hooked up to the rear wheel rims. Two pulling forward two backward. The two on the front hook onto the frame at the already present holes.
If you have every pulled out a vehicle using a chain you can appreciate the jarring that goes on, which is also occurring with your tie down chain.
The staps don't rust or rattle and neither do the metal hooks which are plastic coated.
The other advantage is the ability to increase the safety through multiple (6) fastening points which also spreads the load and strain to the trailer and tractor more evenly.
Give it some thought.
Your bare Bota is about 400 lbs heavier than my BX but seeing how 6 straps are good for 3000+ lbs you should be OK.
Next time I have her loaded I'll post a picture of her.
Happy trailering to you, until we meet again!
