If the RAM had the 8 speed, that's a great transmission.  6 speed??  But anyway, I would pick the Toyota.  Like you say, they are solid.  
I would only buy the RAM if I also bought a lifetime max care contract from Chrysler; it's unlimited mileage coverage and would almost certainly pay off if I kept the truck for the long term (10-20 years).
If you do pick the RAM, I've read that the 5.7L dipstick has historically been off by a quart; oil should be added to the specified quantity, at which point the stick will say it's 1 quart low, but it isn't.
