Hi - I noticed that the sleeve is kinda coming apart. Can someone tell me how bad this is and the importance of getting it fixed?

ps. and yeah I know it looks dirty - I was in a rain storm yesterday - cleaning her this weekend

 

That doesn't look too bad. Clean it up real good and some good electrical tape and maybe some of that corrugated plastic sheathing to protect it.

 

Thanks- What does this do? How will I know if it is ever 'broken". What can I expect if this decides to **** the bed?
