I don't think the 5.7 is too weak, I pulled a big a$$ rock saw, among other things behind my 1/2 ton without any power problems. The tranny is a 4L80E, it's a good auto tranny, and should not give you any trouble. As far as checking the IFS, I would look at the tires and make sure they are wearing evenly, may just be an alignment issue if they are not, but may mean more. Since the truck is I assume stock, I doubt there is any major problems under there though, but if there are, even an untrained I will pick off the obvious. I get great gas mileage with my 5.7 and 33's, so you should get about the same with the 5.7 and 4L80E. Anyway, you could always take it to a mechanic friend to check out before you buy it.
