Well, I found the part number by calling jayco. The round latch with the square head bolt that goes through it and turns it is jayco part #0502230. I called my local campers world that sells Jaycos and they want a whopping $36.89 plus $15.33 shipping for a grand total of $52.22 for the part.
I'll call around and look for a better deal, but that seems really high for a $5 part. If that's my only option I'll have to do it. Hardly the worst expense I'll have with this camper, but sheesh.
Anybody have a good parts guy the recommend I try?
