Sounds like it's done some work, so if fuel delivery is good and fluids are fresh, I might start wondering about compression?
Do you have experience with this model? It is an oldie. It's not weak, but stock 0-60 is in the region of 15 seconds iirc, which tells you something about its rather sedate approach. Saying that, it should have no trouble with hills. 2krpm in 4th should see steady progress on reasonable inclines, but if it's getting as far as "flat out" without pulling, you might also think about a worn clutch?
Then again, it weighs two tons, so its own momentum should see it through a "short hill", which brings us back to drag. Oil emulsifies and thins with use, but if it's sat with any crud in it can gum up and put a fair bit of resistance into the system, so flush fluids : engine (drain, put some cheap oil in, run for a few hundred miles, and renew), gearbox, transfer box, drive units, even swivels/CVs, including refreshing grease in props, UJs, hubs, and check seals too. Wheels up in neutral with handbrake off the props should turn quite freely.
Don't mean to cause panic, just covering the bases, as they say. Start with the easy stuff : props and have a look for signs of compression loss (blowing) at head gasket before testing compression, but fresh fluids is a "must" after sitting for that long.
