I used to pull a large goose neck trailer from job site to job site, some of which were up in the mountains. You just have to get used to being a rolling road block in the right lane, or trade up to a diesel.

If you prefer gas engines, Ford does make larger ones. I don't know the years but some F250s were even equipped with a V10. I had one (V10) in my 2002 F250.

I have the 6.8 V10. 315 hp two valve.
Not huge at all but it pulls pretty good.
All of the "modular" ford engines need to spin pretty fast to make full torque/horsepower.
The V8 super duties have always been underpowered in my opinion.
While they don't make a ton of power, they make enough.
They ARE good tow vehicles.
You just need to keep the revs up!

PS
Ford still offers the V10 3 valve (360 hp I believe) in cab and chassis only.

I would like to echo some others is respect to gas engine rpm. You need to let them work. My 5.7 I force v8 cranks out 380 hp and 401 lbs ft of torque, and to reach that it has a work zone of 2000 to 4000 rpm. Towing flat on interstates its running 2000, and pulling long grades at 60 mph it has a sweet spot at about 3000 rpm. Starting from a stop light on hills I let it wind up to 4000 rpm before shifting to 2nd so I stay up with traffic, after that it revs to about 3200 between shifts so it can deliver the most power. My Tundra also has 4.30:1 gears so with the Six speed tranny it finds optimal torque at 3800, it pulls really well on hills and from stops. So please if you have a Gasser, let'r Rev and let'r shift its just doing its job.

I had a 02 f250 with 5.4l engine. It really wasn't a tire burning truck stock but wasn't a total dog.After a 8" lift kit and 40" tires it really lost it power.i upgraded to a k&n cold air intake,throttle body spacer and it did regain a little pep but nothing to brag about.After if blew out the 3rd spark plug I had a performance shop install 5.4l supercharged engine and tuning and upgraded pulley for more boost,basically the stock lightning engine,took some massaging to get it but it really woke the truck up something fierce.Point being the truck has great tow potential but the engine is your down fall,you can do some simple bolt on performance stuff like custom tuner and the gains may help with towing up hills.If you do deciede to keep go with air bags for the squat,it will ride great with them installed

^ This guy beat me to it. After reading this whole thread this is the first time forced induction was mentioned. If I were the original poster, I would be looking into a bolt on supercharger for that 5.4. That WILL fix the power problems, and since it's already "enough truck" for that trailer I would argue that this is the best, cheapest and most effective fix.
