Eagle , I see nothing wrong with your trailer at all .... It's just you that don't like it .... which of course , I respect ...
But , it's easy to "disguise " anything that doesn't seem right to you ... Like W2 said , a lightweight rack or a fin , or "spoiler" ... And actually that bump might help the airflow moving smoothly over the top, keeping the flow attached ... It does tow well doesn't it ?
You can always start over ...and with all your experience now , I'll bet the next one will be much improved as far as providing you with what you need and want ... The Old one ? Playhouse for the kids , pony palace , dog house , or do like I do and use them for incidental storage when not being used for camping ...
