Never had any problems with our Rpod bath. Ours is only a year old, however. We loved our Rpod and it served us well. However, a PP is correct that someone 6' and above might sleep wall-to-wall in the bed (ours is a 182G).
Our Pod was our first purchase of an RV of any type. We were always tent campers before that... so this was a huge step up for us. I then traded in my TV for something bigger... so since we had the extra tow capacity, we figured why not take advantage... we're currently waiting on delivery of our new Mini Lite 2306.
Honestly, if it were just my wife and I, we'd have kept the Pod and never looked back... and i would say that even a family of 3 would have ample space... but with us being a family of 4 (and we're all the big side), we needed something just a little roomier.
And i will also back up what others have said about the Rpod community mentioned earlier. They're all good people... seriously... every question about anything Pod'ing will be answered.
