#1. Stop worrying about 1,300 EGT. With piston squirter you can go well above 1,500 EGT.

#2. Tune that 7.3 up to give it more fuel and timing.

#3. Put a big wheel turbo on that thing to keep the EGT's down with more fuel timing.

#4. That truck was built for a commercial rating not to haul a small RV around. You have a lot of HP margin to play with.

#5. Go on vacation!

I agree. Intake, exhaust and a good tuner. Should be able to get 400crank hp easily 500 wiTH injectors. The Pistons in that vintage PSD are forged, built to handle a good power boost.

I'm more of a stock kinda guy. Was thinking of the cat at 300 or 330 HP and 800 to 900 ft lbs of torque.

I never thought of a 20K lb toy hauler as a small RV :{) The 99 F550 has a max tow rating of 26K.
As to #5 I'm on it retired in Jan.

You would truly think your 7.3L was a different truck if you upgraded it as suggested here. This has been done many times to these trucks with great success.

We have a fleet of F-650 dump trucks with the 7.2L Cat at my work. On the upside they are very reliable workhorses. On the downside they are somewhat difficult to get in and out of, are very noisy, and have downright ridiculous turbo lag. I would think it would tow your fiver somewhat better than your current truck but not light years better.

JMHO but you have the best diesel Ford ever put in a pick up and you love the truck (I really like that era of Super Duties too). I would do the upgrades to it and be happy.
