We still have some work to do on the interior, might be delayed a bit while we use the camper this summer. I will get some pics soon when we put the overhead cabinets in.
On the ramp ideas. We had an idea just now of making a simple attachment point on our short ramp for the four Rieco Titan 2000 pound camper jacks we currently lift the camper with (and thus carry with us). You could then roll the motorcycle on the ramp while it is level and raise it up to the height of the flatbed using the four camper jacks.
This has some advantages.
1) Easy to build
2) Don't have to buy anything or carry much extra stuff (already carry the jack stands with us)
3) Probably one of the most stable, safest ways to get a bike loaded solo.
4) Doesn't matter if the bike is disabled, as long as it can be pushed on a level surface
If we are in an area where there happens to be a small dune or slope we can back up near, we can just use the 6 foot ramp as a ramp and quickly load/unload.
I do admit it would be pretty slow to load the bikes in this manner, but it is a pretty temporary solution.
