Fancy,
Quicksilver seems to be the only teardrop aimed particularly at motorcycles. Some people here you might want to search on are:
- Roly Nelson (same username), who has built a magnificent 4x8 woodie you will see many photos of, but who has also recently built an ultralight solo teardrop that is exactly what you're looking for, using a 40x48 Harbor Freight trailer kit as the chassis.
- Steve Wolverton (same username) no longer visits this forum but his Cowper design is worth looking up as an example of lightweight building.
- Gerald Hynes (sorry, can't remember his username) from Manitoba has done many miles towing a teardrop behind his Gold Wing (is that a Quicksilver?):
I'll email Gerald to see if he can give his thoughts.
