Did research on that Winebago. Here is what I found out !
Winnebago is working in conjunction with an undisclosed aerospace company to offer an alien technology derived antigravity-plasma thrust winged unit for retrofitting by only authorized dealers with company trained technicians. Leaked information indicates two prototypes are now being tested in Australia. Features a ground effect antigravity buffer field generator in the larger structures next to Winnebago. Power is from U238 wafer block instead of alien used element 115 created by a 5th generation super nova where as earth has 3rd generation mix of elements. Without element 115 only a weak Femions to Bosons spin split is possible. Consequently a near ground antigravity buffer in all that can be sustained (similar to atmospheric ground effect for aircraft). Electron release from the spin split amplified by micron spaced reversed fields powers the two electrogravitic thrusters.
Initial tests indicate maximum antigravity buffering (altitude) will approximate length of Winnebago. Thrusters calibration combined with limited power available from U238 and Winnebago high coefficient of drag will result in speeds approaching 100mph at best. 80mph maximum speed governor is rumored. Thruster power is not all that great, acceleration is mild. Though thrusters run on and on without using gas. Also rumored is a 20-40mph rolling speed before antigravity and thrusters will turn on.
Not only tested, but also likely to be first sold in Australia for vacationing in the outback. U.S. Department of Transportation approval may be problematic.
