Need an opinion(s) from those who have Megacabs.

I have a 2500 Dodge Megacab (not long bed) and have to decide between 2 trailers - Both 20ft.  Difference is the featherlite is aluminum and square nose and titan is steel with tapered nose.  I prefer the Featherlite, but after reading previously posted comments I am concerned about hitting the truck frame/window/etc.  Will the hitch extension fix this sitution on most turns?  Which one will I need or work best?  What about placement of hitch?  or would I be better off going with the tapered nose trailer even though it is steel (not necessarily the one I want but will adapt) but still a good trailer.    Also, never having pulled a tapered nose trailer before does it pull different (wind resistance/etc.) than a square nose trailer?   Any insight would be helpful.  Thank you in advance for your help.
