my rear door has only an exterior rubber seal that isn't even close to working.

How is everyone elses rear door sealed?

Any Ideas how to seal this better?

 

What kind of toy hauler ?

 

My WW has a rubber seal on the door itself. When it shuts it presses against the flat surface of the door frame. No problems with dust or anything else. I pull it on gravel roads and into the mountains in areas where if it leaked it would have done it by now.

What kind of hauler and how does the door fasten?

 

i have a rampage. I have just been putting some duct tape on it...any better ideas?

 

Look on the inside and see if you could install some weatherstriping in the frame perimeter that would press up against the ramp when closed.
