My truck has the rails, the hitch comes out easily enough when I need to move a sofa. My hitch is a manual slider which fortunately I do not need to use if I am careful as the pins are impossible to reach when hooked up (I had an ahem 'mishap' so am REAL careful now). Look for a newer trailer with cutaway corners if your tv has the standard 6 1/2 ft box.
My older Cummins does not have the jake, it would be nice in certain situations but haven't really felt the need for it. The newer diesels have it fitted at the factory but aftermarket is also available. My truck also doesn't have cruise control which would be really nice on the interstates, I also wouldn't have to worry about getting careless and attracting unwanted attention.
