Hi Rexlion,
Those are questions that echoed my own before I bought the trailer. I had never seen one before we moved from SoCal to northern Idaho (Sandpoint). I know that Billy and Sheila, who own the RAH company, have many non- motorcycle people that buy the trailer for car camping.
Probably the answer is that there is more usable space in the trailer. I still have a 10X10 (6 man) Cabelas tent with vestibule. If I set up that size sleeping area it takes up a lot of the floor space.
In the trailer I have the king size bed size plus the 4 X 6 ½ feet of solid floor, and since I can get STUFF out of the basement at any time I don’t have as much clutter.
Incidentally, depending on you emotional ties you can sleep in either direction on that mattress. When we went to Yellowknife Tim slept on the bed slide; it has a 300 lb. weight capacity with the two struts in place. My wife sleeps much closer. :)
The tent obviously sits lower to the ground so the winds are less of a factor but with the trailer I have easily endured 70 mph wind and rain coming off of Lake Osoyoos in BC. I carry a little rope so I just staked out the 4 permanent islets on the trailer and the whole unit was fine. The trailer is waterproof and plus I spray it annually with STARBRITE Marine water proofer.
