stablizer chains when using a 34" hitch extension?

I ended up using turnbuckles in place of chains where it connects to the truck. Its not as nice as running chains at a 45 degree angle but trailer was very stable. I had about 1500 lbs of cargo for a total trailer weight of 2500 lbs. not sure of tongue weight. I'd run this setup any time without worry.

Thanks for the help!
