My names is Fletcher, username is [teardropman]! I am new to this RPOD FORUM, and I am wanting to buy a new, 2016-RPOD-RP-182G. I was just wanting to know, if anyone owning one of these units has had ANY PROBLEMS with watering leaking over the bunk-beds and has anyone had any problems with the , BACK GARAGE DOOR leaking? It will only be me living in it and I will be trading in my big CLASS A on one of these RPODS!!!! Also, what is the true size of the bottom bunk. I will only be using the upper bunk for storage!!! I have a bad back and need to know is there enough room in the bottom bunk to put a, STANDARD SIZE TWIN MATTRESS in place of the one that comes with the new RPOD. I will have to order a special twin mattress because of my bad back!!! Thanks to all for any questions I get and, HAPPY CAMPING TO ALL, ole Fletch in Jax., Fl.
