I like the Leer or Century because of the handle etc. I just think its easier and nicer looking then those that have the key entry on the top. Plus... being on top... make its easier for the lock to freeze in freezing climates with snow.
But the're a bunch of ways you can go. Lot of options.
Mine has a carpet liner... which matches my bed cover... and I absolutely love that.
Also if you can get it... get the 12V light. Light back there is helpful... and if you need more light... you will have a pretty easy source to tap into for LED Strips etc.
