I have the same 5'er and you are going to LOVE it.
We only had/have one problem with ours and that is that a couple different fuses blow on their own with no reason. Especially the one for the keypad on the door. I am picking it back up from the dealer Saturday and hope they found the problem.
Other than that, we had great trips this summer with it. Plenty of storage room in the garage, and when we get there, it makes a great lounging area.
Congrats!!! You won't be sorry.
