I had a similar sized 5th with my 99 F250, I had the 7.3 done up and it towed it like a dream but with the f250 I was 300lbs over my rear axel weight with out the wife and kids so I ended up buying a new truck. with a 1 ton you should be good, but you will be close to maxed out on your rear axel. the 7.3 will handle it good, but in stock configuration you are not going to win any races, I had mine done up to 925 ftlb of torque and a little over 400 hp.
in my case I ended up buying a 2014 f350 so I would be legal, if you are thinking of this but are not sure of the new diesels, don't worry this new 6.7 has less power than my 7.3 b but tows the trailer way better, but your 7.3 should be just fine.

OP's truck may have the same 6K? RGAWR, and that will be the issue he is most likely run up against.
To OP, what size tires does the truck have? LT265/75R16E with 3415 rating are better than the lower rated 17" that became popular as 16" where being phased out.
