Poor Performance when Towing
I recently purchased a 2000 F-350 DRW w/7.3 Diesel for towing my travel trailer. When I am towing on the highway, I find it difficult to accelerate to any more than about 75 mph. Once at this speed, I can maintain it with no problem, but to go any faster for passing or to merge into oncoming traffic in the left lane it becomes difficult.
I have been using my 2000 F-250 for the towing, it has a V-10 and has no problem accelerating to any desired speed when towing the same trailer.
Is there something I could do to achieve the expected(desired) performance from my F-350. The owners manual says the rear end is a 4:10. Would changing the rear end be a possible solution or am I just spoiled because of the performance from my gas V-10.

You must have something wrong with that diesel engine. I can hook up my 13,000 lb 5th wheel and accelorate just fine up to 75 and beyond. Even going uphill. Once I hit a mountain pass then it slows down, but I only have to shift down once. And I have no power mods as of yet. Need to upgrade the exhaust and add some guages first.

Mabye your travel trailer is just REALLY heavy and REALLY wind resistant. I have a stock, 96 3/4ton PSD (this engine has less rated horsepower than your 2000 engine) with a 5spd tranny, a 4:10 gear ratio, a stock pipe with no muffler or cat and a Tymar Intake (which is awesome). I frequently haul a 25 foot horse trailer that usually ends up weighing between 8000 and 10000lbs when its loaded with 2-4 horses, weighing on average 1000lbs. My truck pulls great and accelerates past 75mph easily when I have the opportunity (traveling on the open interstate highways); In fact 73-80 mph is the best speed to pull with my truck in 5th gear (otherwise I usually stay in 4th at about 50-60mph) - my truck's turbo is "spooled up" and Im getting about max torque--that doesn't mean I can't bottom out my speedometer
