I broke off a handle to my propane compartment latch last week by putting the slide out while the compartment door was open!!
My latches look different than these (Alpine 40 FDTS) but I found www.SouthCo.com
on the latch by looking with a magnifying glass. I could identify the latch I wanted from a chart by taking measurments - part #C5-11-45 Sealed Lever Latch. The problem was finding a distributer where I could order just one replacement part. The best I could find wanted $49 for one latch!
Finally found one on eBay for $4 plus shipping from Bontragers Surplus.
