My wife and I are watching "Epic RV's" on the Discovery Channel. They just featured a custom Class A built especially for a pro golfer. It took two years to built and cost $2 million.
The Class A is a two story model. The second story rises like a Hi-Lo but everything inside is just like a TM. The bathroom folds just like a TM. All the interior walls on the second floor folds. It was cool.
