Questions for you end dumpers

Frameless, or frame?
I've never run a frame, we only use frameless.
Air ride or not?
Air ride for sure-much more stable when loaded.
Which is more steady up in the air?
both are bout the same on the frameless end-you dump the bags before rasing the trailer. Too far south to help you on the freezing sand! But a liner is a definite plus!!
