Get the factory skid plates. I believe it comes with the FX4 package as it is much cheaper to order it then to add it later.
Longer beds usually have a larger fuel tank which is a definite plus.
Get 18" tires if possible. The E rated tires have a 3750# rating and will carry your camper nicely.
If possible get the Camper package from the factory.
Enjoy the process!
