Your choice, Blue-OX or Roadmaster, both are first rate, so get what your dealer sells.
Make sure the jeep can be towed first
There are three primary styles
1: Straight "A" frame, hooks to a ball hitch (standard trailer hitch) this is the hardest to hook up unless it has telescoping arms (I've never seen one with telescoping arms)
2: Stow on Jeep, These do have telescoping arms
3: Stow on RV, LIkewise
Telescoping arms means that the arms telescope in and then lock fully extended when you tow So if you are not exactly positioned you can still hook up, and as soon as you move the RV forward the arms extend and lock, Very nice.
DO NOT FORGET to add a supplemental brake system to the jeep, I like the US-Gear Unified Brake Decelerator for tow vehicles without air brakes.
Now to put the 5th up for sale do not need both.
