Top ten glider trailer features?

Torsion axel mounted on rails so the axel can be moved forward or aft. Later you may have more weight forward or aft and moving the axel and inch or two will balance it out having proper weight forward. Also you may move to a location that has a higher driveway and moving the axel back will help eliminate bottoming out. New torsion axels also have the EZ lube. I have switched over every and all trailers I have to synthetic grease. I have a boat so it makes it easier to have one type grease for all trailers, however I also think it is superior and less messy. A shot a grease every year and never will need to replace the bearings.

Sealed lights used on boat trailers with only one connection point that connects lights from front/back and sides with di-electric grease.

Don't reinvent - just make a current model better.
