We use a Tundra reg cab long box to tow our 5th wheel because it has 1820 lbs payload which is the most a Tundra has. We would rather have a double cab incase we want to take others with us but needed the payload. One thing to note is that the Tundra reg cab has much more room behind seat in cab than the other regular cabs so we find that useful as you can get groceries or whatever and still have room in cab. Most other reg cabs end right behind the seat.
My regular cab 2013 RAM 1500 has a cargo space/shelf behind the seat. I am 6' tall, and my seat is nowhere near my back window, or even that shelf thingy. I carry a tool belt behind the passenger seat (in that space) plus have room between the seat and that "shelf" for an emergency kit that includes jumper cables, etc...).
Found a stock photo from a 5500, but my 1500 has the same thing:

The reason you like four doors, is the reason I like two doors. I am never called upon to shuttle people---I keep the center console DOWN, and pretend I do not know that 3rd seat is there :)
