Bathroom doorknob replacement?

[Camp__Forrest__]

We just bought a new (2001) truck camper and the bathroom has a door handle like you would find on an old screen door. Picture a smaller version of the doorknobs in your house. While looking at the camper, my wife and I each hit this thing at least twice. I can picture ripping this off the first time I shove our kayaks inside.

Does anyone have any suggestions for a low-profile replacement. I'm tempted to just replace it with a hook and eye latch.

The Baser door knob is very interesting. I've been looking for something shorter as the bath door and shower door don't clear each other.

Here's a link with a picture of the Baser installed in an RV bath door. http://www.irv2.com/forums/f84/changing-profile-bathroom-door-handle-44242.html

Here's another low profile knob I found, but still might catch on clothes. About $85 with shipping
