David Kroner designed and built the ultimate RV-12 travel trailer. He has proved the effectiveness of his design by taking his RV-12 on the road over long distances safely and without damage. There may be, however a different need for an RV-12 trailer that would be simpler to build and operate and which would fulfill the following objectives:
- Use as a mobile hangar, not for long trips with possibility if allowed to be left inside the airport perimeter, close to the tie down area (this is allowed at my airport for glider trailers)
- Allow solo operation with minimum time required to go from storage to airworthy condition and vice-versa.
- May require more time to stow the plane safely for longer trips but unnecessary for use as a hangar.
It is my belief that this kind of trailer could answer the need of people who do not want to pay for (or cannot get) an airport based hangar.
The critical part is "solo operation", which mostly refers to the wings removal/attachment. I have solved this problem for airport hangar based operation with two contraptions I built (I documented this 2 years ago with a couple of poorly made Youtube videos at :
https://www.youtube.com/watch?v=Z9MnJzHHnDM). I used recently these "wing racks with a twist" during my annual to take the wings off and back on without any help. Something similar would need to be designed that would also be used as a stowing device inside the trailer, not an easy thing to do!
If all these design requirements could be solved the great RV-12 feature of easily removable wings would reach it's ultimate benefit.
