YES! We love to RV and so do our 2 boyz! I work, but am off in the summer - so our trips other than in the summer are short. But in the summer, we usually go out for a month or two. The boyz have a blast.
The only thing they don't like so much is always being on-leash in the RV parks. At home, we have a doggie door and someone is home here with them 95% of the time, so they can run in and out and around the yard to their hearts content. I know that they get tired of not being able to run free while we are in the RV.
We take 2 X-pens with us and put them together for a larger area so that they can get in there and run. BUT, they want me to sit in there with them!!!
So, sometimes I put my lawn chair in there and sit and then they run circles around me!
Last summer we saw someone in the RV park with maybe 3 or 4 X-pens all together and they set them up under the RV steps (they cut them shorter so that they would fit under the steps) to go out from the front door of the RV, making a big circle fenced "yard" in the front of the RV, so that you could open the RV door and they could go outside into the "fenced yard" without being on leash. Then there was a swing-door in the pen for the "humans" to get out of the X-pen. It looked GREAT and I think we may try that this summer.
