Max towing with C-10 'Burb

[Average Joe]

I recently aquired a 25' travel trailer with a gross weight rating of 6600# and dry weight of 5500#. I am going to pull said trailer with my '67 c10 suburban. I was planning on swapping out my 283 for the 454 in my pickup for some time and this just clinched the deal. Power wise I think I'll be fine after the motor swap but I am concerned about the 600 pound tongue weight and overall handling especially with rear coils. I will be using load bars and sway control device as well. The trailer is very well balance and towed like a dream behind my buddies diesel Excursion with no sway bars for the ride home. But that thing is a freakin tank! Are auxillary air bags in my future? Rear sway bar? Aftermarket c- clip eliminator axles? I guess I'm just curious as to what setups you guys are using. Thanks for any input.
